+<p>当我在打植物大战僵尸时，爸爸说他抗原检测阳性了。</p>
+<p>妈妈就让他隔离在他的房间，然后拿出了各种什么东西消杀病菌啥的。</p>
+<p>比如说放了什么艾灸的东西在那熏。目前感觉还行，就是被熏的鼻子干还有点呛...</p>
+<p><strong>2022年12月15日</strong></p>
+<p>早上没啥感觉，到晚饭前感觉有点累，不确定是玩了会累了还是发作了...</p>
+<p><strong>2022年12月16日~2022年12月18日</strong></p>
+<p>发烧，头疼得不得了，手酸腿酸就跟死了一样</p>
+<p>应该是18号这一天最绝望了，咽东西都喉咙痛，痛的要死，折磨人。</p>
+<p><strong>2022年12月19日</strong></p>
+<p>早上还有点喉咙痛，但基本上变成咳嗽了，咳得起飞</p>
+<p><strong>2022年12月20日~2022年12月21日</strong></p>
+<p>咳得起飞，昏昏沉沉学不进</p>
+<p><strong>2022年12月22日~2022年12月30日</strong></p>
+<p>反正就一直咳咳咳，咳啊咳，没完没了一样</p>

+<p>Linux cp（英文全拼: copy file）命令主要用于复制文件或目录。</p>
+<p><strong>语法</strong>：</p>
+<pre class="line-numbers language-none"><code class="language-none">cp [options] source dest<span aria-hidden="true" class="line-numbers-rows"><span></span></span></code></pre>
+<p>或者</p>
+<pre class="line-numbers language-none"><code class="language-none">cp [options] source... dest<span aria-hidden="true" class="line-numbers-rows"><span></span></span></code></pre>
+<p><strong>参数说明</strong>：</p>
+<pre class="line-numbers language-none"><code class="language-none">-a：此参数的效果和同时指定&quot;-dpR&quot;参数相同；
+-d：当复制符号连接时，把目标文件或目录也建立为符号连接，并指向与源文件或目录连接的原始文件或目录；
+-f：强行复制文件或目录，不论目标文件或目录是否已存在；
+-i：与-f相反，覆盖既有文件之前先询问用户；
+-l：对源文件建立硬连接，而非复制文件；
+-p：保留源文件或目录的属性；
+-R&#x2F;r：递归处理，将指定目录下的所有文件与子目录一并处理；
+-s：对源文件建立符号连接，而非复制文件；
+-u：使用这项参数后只会在源文件的更改时间较目标文件更新时或是名称相互对应的目标文件并不存在时，才复制文件；
+-S：在备份文件时，用指定的后缀“SUFFIX”代替文件的默认后缀；
+-b：覆盖已存在的文件目标前将目标文件备份；
+-v：详细显示命令执行的操作。<span aria-hidden="true" class="line-numbers-rows"><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span></span></code></pre>

+<p>在使用 <code>ls -a</code> 命令的时候，我们会发现任何目录下都有
+<code>.</code> 和 <code>..</code> 两个文件。</p>
+<p>事实上，Linux 系统的目录下一定会有 <code>.</code> 和 <code>..</code>
+两个文件， 只有这两个文件的目录就是空目录。</p>
+<p>这两个文件可以被归纳为特殊文件，但是其本质和普通文件没有区别，只是名字独特而已。</p>
+<p>其中 <code>.</code> 文件是用于指代目录本身，而 <code>..</code>
+是用于指代目录的上级（<del>像不像每个节点都有自环的一棵树</del>）</p>
+<p>仔细想想也是，我们有 <code>cp -r source/. dest</code> 和
+<code>cd ..</code> 这种指令，对吧。</p>
+<p>阅读参考文献[1]，个人认为这种设计是为了某种完整性或者说统一性，</p>
+<p>比如我们建混合图的时候不是无向边和有向边分类建，而是把无向边看作两条有向边。</p>

+采蘑菇</a></p>
+<blockquote>
+<p><strong>题意</strong>：</p>
+<p>q779 和 cxy 要去森林采蘑菇。</p>
+<p>森林间有 <span class="math inline">\(N\)</span> 个小树丛，<span
+class="math inline">\(M\)</span>
+条小径，每条小径都是单向的，连接两个小树丛，上面都有一定数量的蘑菇。q779
+和 cxy
+经过某条小径一次，可以采走这条路上所有的蘑菇。由于森林是一片神奇的沃土，所以一条路上的蘑菇被采过后，又会长出一些新的蘑菇，数量为原来蘑菇的数量乘上这条路的“恢复系数”
+<span class="math inline">\(c\)</span> ，再下取整。</p>
+<p>比如，一条路上有 <span class="math inline">\(4\)</span>
+个蘑菇，这条路的“恢复系数”为 <span class="math inline">\(c =
+0.7\)</span>，则第一~四次经过这条路径所能采到的蘑菇数量分别为 <span
+class="math inline">\(4,2,1,0\)</span> 。</p>
+<p>现在，q779 和 cxy 从 <span class="math inline">\(S\)</span>
+号小树丛出发，求他们最多能采到多少蘑菇。</p>

+<p>因为 NOIP2022 失利，错失省一，遗憾退役。</p>
+<p>但是我又找到了一条适合我的路，因此有了这篇文章。</p>
+<p>其实并没有真正复活，因为最多是高三去参加一次 NOIP 了。</p>
+<p>但是我现在觉得，作为一个普普通通的人，拿到 NOIP 省一也是光荣的。</p>
+<p>是的，我决定休学一年，不仅是找到某种生活的意义，更是一种自我提升的尝试</p>
+<p><br></p>
+<p>怎么说呢，总觉得我的人生被疫情彻彻底底的改变了。或者说，被三个阶段的网课改变了。</p>
+<p>第一次的网课，我记得很清楚，当时是2020年的上半年，我还没有真正接触竞赛。</p>
+<p>那个时候的我还是挺活泼开朗的人，保持着童年的某种纯真吧，因此比较喜欢和别人一起玩</p>
+<p>结果突然而来的网课，加上我的“朋友”要么没手机，要么没空，总之就是很孤独的一段时间。</p>
+<p>因为没有真正爱上什么东西，所以时间大多在游戏中耗费了，不过那个游戏现在甚至没了。</p>
+<p>曾和我一起打了几局游戏的“朋友”，不过是把我当傻子耍，到最后果然只有我荒度了几个月。</p>
+<p>从那以后，我的历史道法就再也没追上来过，好在最后中考表现的不算特别烂</p>
+<p>我不知道我在暑假真正接触 OI
+之前的日子是怎么度过的，也许在拼命补文化课吧。</p>
+<p><br></p>
+<p>接触了 OI 之后，可以说我彻彻底底的改变了。</p>
+<p>前行的动力出现了，那是一种充满恨意的感觉，尽管我不知道为什么会有这种感觉。</p>
+<p>这一段时光还是比较有趣的，我应该在其它的文章中记录过。</p>
+<p>第二段网课是我 OI
+进步飞快的一段时间吧，可以说是献祭流，利用网课达到了停课的效果。</p>
+<p>不过因为长期自学，一开始没有很重视刷题，所以基础不是很好，这也是 NOIP
+翻车的主要原因。</p>
+<p>后来，越到 NOIP 接近，越是感觉时间不够，不过我还是在很努力学的。</p>
+<p><br></p>
+<p>再后来，就是退役了。我看到了曾经比我弱的同学考出了更好的成绩，看到了他们得到成功，</p>
+<p>而我失去了一切，这不是我所期望的，这不是我所应得的，这不是我努力应该得到的结果。</p>
+<p>我像无数失败者一样感到了一种绝望，一种灵魂被抽走的空洞感，是信仰崩塌的感受。</p>
+<p>我不想回到紧张忙碌的学习生活中，但是对信息学的热爱又让我难以放弃自己的大好未来。</p>
+<p>有趣的是，这时候正好来了第三次网课，尽管我一节都没有上。</p>
+<p>在网课之前，我请了很长的假，补了一些文化课，但更多的是一种无法释怀的感受</p>
+<p>读了我 blog 的同学应该注意到了 covid-19 感染记。</p>
+<p>在感染新冠期间，我体会了一种肉体和精神上的双重折磨。</p>
+<p>在好一些的时候，买了个 RTX3070 的新笔记本用来打游戏和兼容性需求。</p>
+<p>玩了好一段时间，就是啥也不想干。但是玩并没有让我感到真正的快乐。</p>
+<p>不过，好在我思考了很多很多，每天晚上都在思考着，怎么才能找回之前的自己。</p>
+<p>直到我重新开始了 OI
+，不能说我完全想开了，但是我似乎找到了一种新生活。</p>
+<p>当我放下了给自己的巨大压力，我能感受到一种为了自己所热爱的东西而活着的感受。</p>
+<p>我不知道这种感受能持续多久，但是我能感受到，我内心的伤痕在愈合。</p>
+<p>这种力量似乎并不是曾经的恨，也不是单纯对未来的美好幻想感。</p>
+<p>很难体会这种新的感受，也许我会在未来理解它？至少，我觉得现在不能很好理解它。</p>
+<p><br></p>
+<p>也许是时候按下暂停键了，希望在这一年内我能在 OI
+和文化课上都有进步。</p>
+<p>对我来说，除了 cxy 以外，大概我也没有什么真正的好朋友了。</p>
+<p>所以希望 cxy 在新的一年也能取得好成绩（滑稽</p>
+<p>2022年12月31日 00:48:43 记</p>
+<hr />
+<p><strong><em>“当上帝关了这扇门，一定会为你打开另一扇门”</em></strong></p>
+<p>说实话，虽然我没有抱有这样的期待，但是它奇迹般地发生了。</p>
+<p>是的，我多了一次完整的比赛的机会。如果我能发挥好的话，还是很有希望的。</p>
+<p>加油，虽然努力不一定会改变什么，但是不努力一定改变不了。</p>

+[USACO13NOV] No Change G</a></p>
+<blockquote>
+<p><strong>题意</strong>：</p>
+<p>Farmer John 在市场上为他的农场购买物资。 他的口袋里有 <span
+class="math inline">\(k\)</span> 个硬币 <span class="math inline">\((1
+\le k \le 16)\)</span> ，每个硬币的价值在<span
+class="math inline">\(1\sim 10^8\)</span> 范围内。 FJ 想进行一连串的
+<span class="math inline">\(n\)</span> 次购买 <span
+class="math inline">\((1 \le n \le 10^5)\)</span> ，其中第 <span
+class="math inline">\(1\)</span> 次购买需要花费 <span
+class="math inline">\(c_i\)</span> 个单位的钱<span
+class="math inline">\((1 \le c_i \le 10^4)\)</span> 。
+当他进行这一连串的购买时，他可以定期停下来，用一枚硬币来支付自他上次付款以来的所有购买（当然，他使用的这枚硬币必须足够大，以支付所有这些购买）。
+不幸的是，市场上的小贩完全没有零钱，所以每当 FJ
+使用大于他所欠的钱的硬币时，他都很遗憾地没有收到任何零钱的回报！请计算出最大的金额。</p>
+<p>请计算 FJ 在依次进行了 <span class="math inline">\(n\)</span>
+次购买后，最终能得到的最大金额。 如果 FJ 不可能完成他所有的购买，则输出
+<span class="math inline">\(-1\)</span>。</p>
+<p><strong>输入格式</strong>：</p>
+<p>第 <span class="math inline">\(1\)</span> 行，两个整数，<span
+class="math inline">\(k\)</span> 和 <span
+class="math inline">\(n\)</span> 。</p>
+<p>第 <span class="math inline">\(2\ \sim \ k+1\)</span> 行，每一行包含
+FJ 的一个硬币的金额。</p>
+<p>第 <span class="math inline">\(2+k\ \sim \ n + k + 1\)</span> 行，这
+<span class="math inline">\(n\)</span> 行包含 FJ
+打算购买的东西的费用。</p>
+<p><strong>输出格式</strong>：</p>
+<p>第1行，FJ 最终能得到的最大金额，如果 FJ 不能完成所有的购买，则输出
+<span class="math inline">\(-1\)</span>。</p>
+</blockquote>
+<p>得到的最大金额一定时，硬币的状态不唯一，因此不能二分。</p>
+<p>于是考虑枚举所有的状态，但是每次都暴力检验复杂度太高了</p>
+<p>注意到很多的状态之间存在联系，比如某个状态不能成功购买，但是后面加上了几个硬币就能买了</p>
+<p>设 <span class="math inline">\(f_i\)</span> 表示状态为 <span
+class="math inline">\(i\)</span>
+时最多能买到几号物品。不妨记每个硬币的面额为 <span
+class="math inline">\(v_i\)</span> 。</p>
+<p>状态可以转移至 <span class="math inline">\(f_j\)</span> 当且仅当
+<span class="math inline">\(j = i\, \cup\,\{k\},~k \in (\sim i)\)</span>
+。记 <span class="math inline">\(r=p\)</span> 为使得 <span
+class="math inline">\(\sum_{t = f_i}^{r} v_t \le w_k\)</span>
+成立的最大值，则 <span class="math display">\[
+f_j \uparrow p
+\]</span> 这个 <span class="math inline">\(p\)</span>
+可以二分得到，只需要预处理下 <span class="math inline">\(v_i\)</span>
+的前缀和。并且当某个 <span class="math inline">\(f_i = n\)</span>
+时，尝试更新一下当前的答案。</p>
+<p>时间复杂度 <span class="math inline">\(\mathcal{O}(2^kk \log
+n)\)</span></p>

+                <h1 id="认知偏差的危害">认知偏差的危害</h1>
+<p>今天看到一个新闻，大概是：我国自 2026 年起，水银温度计全面禁产</p>
+<p>首先我感到很惊讶，这么好用的东西为什么要禁产呢？</p>
+<p>而且我一直都是用水银温度计的，因为电子测温计公认的不准确</p>
+<p>这时候就产生了一种认知偏差，我不希望别人改变我的生活习惯，因此我会不假思考地反对这个政策。</p>
+<p>就在我很愤怒的准备抨击这个政策时，我看到了一个评论</p>
+<p><img src="https://raw.githubusercontent.com/q779/blog-img/main/img/202301010109313.png" style="zoom:50%;" /></p>
+<p>事实上，一开始我并不想看这个评论，因为跟我观点不同</p>
+<p><del>但是理性的处事态度让我静下来读了这个评论</del>，说得很有道理，而且这个政策确实是早就有的了。</p>
+<p>水银温度计摔碎导致的水银泄露对人体会有一定的危害，同时不当的处理方式会导致环境污染。</p>
+<p>当然了，这个评论也不是完全正确的，我觉得写新闻的人可能是趁最近体温计关注比较多，蹭蹭流量罢了</p>
+<p>之所以我会中了别人的计，首先是认知偏差，其次是无知（因为我不知道有无汞体温计）</p>
+<p>目前我没有想到特别好的办法应对这种认知偏差，因为这是人的本能。</p>
+<p>不过我想到了一个比较好的办法，那就是<strong>在决策会造成一定程度影响时，要求自己冷静思考</strong>。</p>
+<p>比如我要是发表了一些不当言论，很有可能会给自己带来不必要的麻烦，所以我需要在这之前冷静思考一下。</p>
+<p>说白了就是从小被教导的“三思而后行”，但是真正做到的又占多少呢？总之希望我的文章可以帮助到你们。</p>

+<p>复活后的第一道黑题，有一说一难度确实很高。</p>
+<p>首先考虑 <span class="math inline">\(l,r\)</span>
+相差较小的情况，可以考虑对 <span class="math inline">\([l,r]\)</span>
+间的所有数字建 <span class="math inline">\(\mathtt{AC}\)</span>
+自动机，然后在上面跑 dp 统计答案。</p>
+<p>考虑节点 <span class="math inline">\(i\)</span> 代表的串对答案的贡献
+<span class="math inline">\(g_i\)</span> ，则 <span
+class="math inline">\(g_i\)</span> 为节点 <span
+class="math inline">\(i\)</span> 跳失配指针能到的点的贡献总和，即 <span
+class="math display">\[
+\begin{aligned}
+g_v \uparrow g_{\texttt{fail}_v} &amp;&amp;&amp;&amp;\big(a\uparrow b :=
+a \gets a + b\big)
+\end{aligned}
+\]</span> 设 <span class="math inline">\(f_{i,j}\)</span> 表示在节点
+<span class="math inline">\(j\)</span> 上组成 <span
+class="math inline">\(i\)</span> 位数的方案数，显然可以拿 <span
+class="math inline">\(f_{l,u} + g_v\)</span> 来更新 <span
+class="math inline">\(f_{l+1,v}\)</span> ，答案就是 <span
+class="math inline">\(\max f_{n,i}\)</span></p>
+<p>但是这里 <span class="math inline">\(l,r\)</span>
+相差巨大，所以不能直接暴力建 <span
+class="math inline">\(\mathtt{AC}\)</span> 自动机。</p>
+<p>容易发现，暴力 <span class="math inline">\(\mathtt{AC}\)</span>
+自动机中有很多节点，以它为根的子树都是一个<strong>满十叉树</strong>，而这些树并不那么有用。</p>
+<p>例如 <span class="math inline">\([1000,2333]\)</span> 间，枚举到
+<span class="math inline">\(11\_\,\_\)</span>
+时，后面怎么填都行，而我们朴素dp会把每个都跑一次。</p>
+<p>显然我们会想到把这些节点缩起来。考虑将一个深度为 <span
+class="math inline">\(l\)</span> 的满十叉树缩成一个点（有 <span
+class="math inline">\(10^{l}\)</span> 个叶结点的满十叉树）</p>
+<p>于是，当走到这个点的时候，再任意走 <span
+class="math inline">\(l\)</span> 步（但是至少走 <span
+class="math inline">\(l\)</span>
+步才能产生贡献），就一定能产生一个匹配</p>
+<p>也就是说我们对这个根节点打上一个长度为 <span
+class="math inline">\(l\)</span> 的标记，表示只要再走 <span
+class="math inline">\(l\)</span> 步就可以得到 <span
+class="math inline">\(1\)</span> 的贡献</p>
+<p>当然，一个点可能被打上多个标记。因此实际上，我们对一个点存储的信息是：长度为
+<span class="math inline">\(l\)</span> 的标记的数量。</p>
+<p>这样就比刚才的更好更早多了，可以通过 <span
+class="math inline">\(\mathtt{dfs}\)</span>
+构造，思想类似于数位dp，详见代码。</p>
+<p>对于 dp 的转移，只需要枚举下一个字符是 <span
+class="math inline">\(\mathtt{0 \sim 9}\)</span> 中的哪一个，然后去
+<span class="math inline">\(\mathtt{AC}\)</span> 自动机上跑，</p>
+<p>再根据当前串长 <span class="math inline">\(l\)</span>
+决定加入哪些标记。具体地，设串长为 <span
+class="math inline">\(l\)</span> ，则长度小于 <span
+class="math inline">\(l\)</span> 的标记都是有效的，考虑前缀和处理。</p>
+<p>最后就是输出方案的问题，因为要求字典序最小，而传统的转移方向会求出翻转后字典序最小的串。</p>
+<p>因此考虑换一个转移方向。用 <span
+class="math inline">\(f_{i,j}\)</span> 表示总长度为 <span
+class="math inline">\(i\)</span> 的串，<strong>初始时自动机在位置 <span
+class="math inline">\(j\)</span></strong> 所可以获得的最大权值。</p>
+<p>这里的区别在于：一般是默认从 <span
+class="math inline">\(\mathtt{AC}\)</span>
+自动机的根出发，枚举最后到了哪里。</p>
+<p>设自动机转移 <span class="math inline">\(j \to k\)</span> ，则我们用
+<span class="math inline">\(f_{i+1,k}\)</span> 去更新 <span
+class="math inline">\(f_{i,j}\)</span>
+，这样就可以顺便记录选哪个字符更优，从而输出方案</p>
+<p>时间复杂度 <span class="math inline">\(\mathcal{O}(n \log r \cdot
+\Sigma^2)\)</span> ，其中 <span class="math inline">\(\Sigma=10\)</span>
+为字符集大小，<span class="math inline">\(r = 10^{800}\)</span>
+为值域。</p>

+<p>这个系列终于来了😎，虽然不是什么卡常带师，但是还是有点东西可以写的。</p>
+<p>主要是今天看到了很多奇奇怪怪的优化方法，所以还有一些东西需要慢慢补。</p>
+<hr />
+<h2 id="一输入优化">一、输入优化</h2>
+<p>咕咕咕。</p>
+<hr />
+<h2 id="二输出优化">二、输出优化</h2>
+<p>咕咕咕。</p>
+<hr />
+<h2 id="三位运算优化">三、位运算优化</h2>
+<p>这里是最魔幻的，<del>我记得 yukuai26
+老师说他们大二的时候会讲一堆奇奇怪怪的优化</del>。</p>
+<ol type="1">
+<li><p><code>char型数字</code> 转 <code>int型数字</code>
+（卡常效果：微小）</p>
+<pre class="line-numbers language-cpp" data-language="cpp"><code class="language-cpp"><span class="token keyword">char</span> x <span class="token operator">=</span> <span class="token char">'1'</span><span class="token punctuation">;</span>
+cout <span class="token operator">&lt;&lt;</span> <span class="token punctuation">(</span>x <span class="token operator">&amp;</span> <span class="token number">15</span><span class="token punctuation">)</span><span class="token punctuation">;</span> <span class="token comment">// 输出的是：1</span><span aria-hidden="true" class="line-numbers-rows"><span></span><span></span></span></code></pre>
+<p>原理：一般的写法是 <code>x = x - '0'</code> ，众所周知字符 <span
+class="math inline">\(\tt{0}\)</span> 对应的 ASCII 码是 <span
+class="math inline">\(48\)</span> 。</p>
+<p>而 <span class="math inline">\(48 = 32 + 16\)</span>
+，正好是二进制下第 <span class="math inline">\(5,6\)</span> 位，而 <span
+class="math inline">\((15)_{10} = (1111)_2\)</span></p>
+<p><span class="math inline">\(x\&amp; 15\)</span> 就是取了一个在 <span
+class="math inline">\(48\)</span>
+上的增量，这个用法仅适用于数字型。</p></li>
+</ol>
+<hr />
+<h2 id="四指针优化">四、指针优化</h2>
+<ol type="1">
+<li><p>访问 <code>a[0]</code> 可以写成 <code>*a</code>
+（卡常效果：微小）</p>
+<p>原理：<code>a[x]</code> 本质上就是 <code>*(a + x)</code> （所以写
+<code>x[a]</code> 都可以😶‍🌫️）</p></li>
+</ol>
+<hr />
+<h2 id="五其他优化">五、其他优化</h2>
+<ol type="1">
+<li><p>手写常见数据结构，例如 <code>queue</code> 、<code>vector</code>
+等（卡常效果：开 O2 后不确定，有时候会反向优化）</p></li>
+<li><p>把 <code>if(xxx) yyy</code> 改成 <code>xxx &amp;&amp; yyy</code>
+（卡常效果：极微小， 但是很美观😶‍🌫️）</p></li>
+</ol>

+<p>本文是简单教程，如果您对ps比较了解，那么您可以做到更好的效果。</p>
+<hr />
+<p><del>PS 不咋会用的菜鸟终于p出点花样来了，真不容易</del></p>
+<p>用于修复的网站是 <a target="_blank" rel="noopener" href="https://app.aimages.ai/images">Aimages</a>
+，一个 AI 修复的网站，比较好用。</p>
+<p>upd.如果您的显卡比较好的话，可以去用<a
+target="_blank" rel="noopener" href="https://github.com/AaronFeng753/Waifu2x-Extension-GUI/blob/master/README_CN.md">这个</a>本地修复，开源的。</p>
+<p>考虑放大一张壁纸的清晰度，这里用下面这张图作示例。顺便建议 mac
+用户把颜色描述文件调成 sRGB 。</p>
+<p><img src="https://raw.githubusercontent.com/q779/blog-img/main/img/202301041219763.jpg" style="zoom:50%;" /></p>
+<p>首先，如果我们直接把原图放上去修复，会变成这种样子</p>
+<p><img src="https://raw.githubusercontent.com/q779/blog-img/main/img/202301041225780.jpg" style="zoom:67%;" /></p>
+<p>放大上面那幅图，会发现图片有非常多密密麻麻的点（<del>有点恶心啊</del>）</p>
+<p><img src="https://raw.githubusercontent.com/q779/blog-img/main/img/202301041226346.png" style="zoom:67%;" /></p>
+<p>这个问题的原因在于：<strong>原图有非常多的杂色</strong>，我们看看原图</p>
+<p><img src="https://raw.githubusercontent.com/q779/blog-img/main/img/202301041228802.png" style="zoom:67%;" /></p>
+<p>有没有发现，特别是眼睛的地方，比如那块高光有好多杂点。</p>
+<p>所以我们要先在修复之前先去除原图的杂点。（本地跑好像也会有这个问题）</p>
+<p>我看他们专业的有好复杂的方法，不过我这有个简单的办法：选择
+<code>[滤镜] &gt; [Camera Raw 滤镜]</code>。</p>
+<p>如果你的 PS 没有这个的话，要么升级一下版本，要么<a
+target="_blank" rel="noopener" href="https://helpx.adobe.com/cn/camera-raw/kb/camera-raw-plug-in-installer.html">打个补丁</a>。（<del>记得忽略图片里的歌词</del>）</p>
+<p><img src="https://raw.githubusercontent.com/q779/blog-img/main/img/202301041231867.png" style="zoom:50%;" /></p>
+<p>然后就到了这个界面，调的话凭感觉就行，没有固定数值</p>
+<p><img src="https://raw.githubusercontent.com/q779/blog-img/main/img/202301041235432.png" style="zoom:50%;" /></p>
+<p>然后导出，再丢到 Aimages
+里面修复一下，就可以得到下图啦！（<del>很好，我又多了一个高清壁纸</del>）</p>
+<p><img
+src="https://raw.githubusercontent.com/q779/blog-img/main/img/202301041237784.jpg" /></p>
+<p>这里我用 RTX3070
+本地跑了一下，用的模型是最后一个，然后稍微开了点降噪啥的，效果更好</p>
+<p><img
+src="https://raw.githubusercontent.com/q779/blog-img/main/img/202301281432698.jpg" /></p>
+<p>下面是我用更复杂的ps方法得到的更好的图像，也就是抠出多个图层然后分情况去杂色，最后再改一下颜色啥的</p>

+[HNOI2002]公交车路线</a></p>
+<blockquote>
+<p><strong>题意</strong>：</p>
+<p>在幻想郷新建的环城公路上一共有 <span class="math inline">\(8\)</span>
+个公交站，分别为 A、B、C、D、E、F、G、H。</p>
+<p>公共汽车只能够在相邻的两个公交站之间运行，因此你从某一个公交站到另外一个公交站往往要换几次车，例如从公交站
+<span class="math inline">\(A\)</span> 到公交站 <span
+class="math inline">\(D\)</span>，你就至少需要换 <span
+class="math inline">\(3\)</span> 次车。</p>
+<p><img src="https://raw.githubusercontent.com/q779/blog-img/main/img/202301082005890.png" style="zoom:33%;" /></p>
+<p>不过琪露诺的方向感极其糟糕，我们知道从公交站 <span
+class="math inline">\(A\)</span> 到公交 <span
+class="math inline">\(E\)</span> 只需要换 <span
+class="math inline">\(4\)</span> 次车就可以到达，而她却总共换了 <span
+class="math inline">\(n\)</span> 次车！</p>
+<p>注意琪露诺一旦到达公交站 <span
+class="math inline">\(E\)</span>，她不会笨到再去换车。现在希望你计算一下琪露诺有多少种可能的乘车方案。</p>
+<p><strong>输入格式</strong>：</p>
+<p>仅有一个正整数 <span
+class="math inline">\(n\)</span>，表示琪露诺从公交车站 A 到公交车站 E
+共换了 <span class="math inline">\(n\)</span> 次车。</p>
+<p><strong>输出格式</strong>：</p>
+<p>输出一个正整数表示方案数，由于方案数很大，请输出方案数除以 <span
+class="math inline">\(1000\)</span> 后的余数。</p>
+<p><strong>数据范围</strong>：</p>
+<p><span class="math inline">\(4\le n\le10^7\)</span>。</p>
+</blockquote>
+<p>首先从 <span class="math inline">\(E\)</span> 断环为链，因为走到
+<span class="math inline">\(E\)</span> 以后不会再换车。</p>
+<p>此时的公交线路就关于 <span class="math inline">\(A\)</span>
+对称了，容易发现相对称的两个站点方案数是相同的。</p>
+<p>故我们只对 <span class="math inline">\(A \sim D\)</span> 做一遍dp。设
+<span class="math inline">\(f_{i,j}\)</span> 表示走了 <span
+class="math inline">\(i\)</span> 步到 <span
+class="math inline">\(j\)</span> 的方案数，则有 <span
+class="math display">\[
+f_{i,j} = f_{i-1,j-1} + f_{i-1,j+1}
+\]</span> 稍微滚滚数组就好啦，时间复杂度 <span
+class="math inline">\(\mathcal{O}(n)\)</span> ，代码如下：</p>

+<p>网线外皮一般都会印有CAT5、CAT5 E、CAT6、CAT7和CAT8等字样</p>
+<p>对应的网线类型是五类线、超五类线、六类线、七类线和八类线。</p>
+<p>其中，五类线是百兆网线，超五类线和六类线是千兆网线，七类线是万兆网线，八类线是十万兆网线。</p>
+<hr />
+<p>（<del>以下改编自真实事件</del>）</p>
+<p>有人会说了，为啥我网线是千兆网线，但是网速这么慢呢？</p>
+<p>那就得看你买了多少兆的网络，以及你的路由器啊调制解调器啊是否支持这个速度</p>
+<p>如果都达到了配置，那么你的电脑网卡是否支持这个网速呢</p>
+<p>如果也ok，那很有可能是路由器不好，家里干扰的东西太多，可以换个路由器试试（</p>

+2.1应用层协议原理</h1>
+<p>研发网络应用程序的核心是写出能够运行在不同的端系统和通过网络彼此通信的程序。</p>
+<p>事实上，即使你要为网络核心设备写应用程序软件，也是做不到的，因为他们在网络层及以下层次起作用</p>
+<p>这种基本设计，即将应用软件限制在端系统的方法，促进了大量网络应用程序的快速研发和部署。</p>
+<hr />
+<h2 id="网络应用程序体系结构">2.1.1 网络应用程序体系结构</h2>
+<p>当进行软件编码之前，应当对应用程序有一个宽泛的体系结构计划。</p>
+<p>请记住应用程序的体系结构明显不同与网络的体系结构，例如因特网体系结构等</p>
+<p>从应用程序研发者的角度看，网络体系结构是固定的，并为应用程序提供了特定的服务集合</p>
+<p>在另一方面，<strong>应用程序体系结构</strong>由应用程序研发者设计，规定了如何在各种端系统上组织该应用程序</p>
+<p>在选择应用程序体系结构时，应用程序研发者很可能利用现代网络应用程序中所使用的两种主流体系结构之一</p>
+<p>即 客户—服务器体系结构 或
+对等（P2P）体系结构。下面我们来详细介绍一下这两种体系结构：</p>

+<p><strong>客户—服务器体系结构</strong>是常见的体系结构。例如在 Web
+应用程序中，有两个相互通信的不同程序，</p>
+<p>一个是运行在用户主机上的浏览器程序，另一个是在 Web 服务器主机上运行的
+Web 服务器程序</p>
+<p>用户主机不是唯一的，我们通常也称为客户主机。而总是打开的 Web
+服务器主机服务于浏览器的请求</p>
+<p>当 Web
+服务器接受到来自某客户（通过浏览器）对某对象的请求时，它向该客户发送所请求的对象作为响应</p>
+<p>值得注意的是利用客户—服务器，客户相互之间不直接通信。</p>
+<p>客户—服务器体系结构的另一个特征是：该服务器具有固定的、周知的地址，该地址称为
+IP 地址。</p>
+<p>该特征使得客户总是能通过向该服务器的 IP 地址发送分组来与其联系。</p>
+<p>具有客户—服务器体系结构的非常著名的应用程序包括 Web、FTP、Telnet
+和电子邮件。</p>
+<p><img src="https://raw.githubusercontent.com/q779/blog-img/main/img/202301141809730.jpg" style="zoom: 33%;" /></p>
+<p>在一个客户—服务器应用中，常常会出现一台单独的服务器主机跟不上它所有的客户请求的情况</p>
+<p>例如，一个流行的社交网络站点如果仅有一台服务器来处理所有请求，将很快变得不堪重负。</p>
+<p>为此，配备大量主机的<strong>数据中心</strong>常被用于创建强大的虚拟服务器。</p>
+<p>显然，数据中心可以有多个，并且一个数据中心可以有数十万台服务器，可以想象其互联和带宽费用的巨大。</p>
+<p><br></p>
+<p>在一个 <strong>P2P 体系结构</strong>
+中，对位于数据中心的专用服务器有最小的（或者没有）依赖</p>
+<p>相反，应用程序在间断连接的主机对之间使用直接通信，这些 主机对 被称为
+<strong>对等方</strong> 。</p>
+<p>这些对等方并不为服务提供商拥有，相反缺位用户控制的桌面机和膝上机
+(laptop) 所有</p>
+<p>因为这种对等方通信不必通过专门的服务器，所以该体系结构被称为对等方到对等方的。</p>
+<p>许多目前流行的、流量密集型应用都是 P2P 体系结构的。</p>
+<p>包括文件共享（如 BitTorrent
+）、对等方协助下载加速器（如迅雷）、因特网电话和视频会议（如
+Skype）等</p>
+<p>需要注意的是，某些应用具有混合的体系结构，它结合了客户—服务器和 P2P
+的元素</p>
+<p>例如，对于许多即时讯息应用而言，服务器被用于跟踪用户的 IP地址，</p>
+<p>但用户到用户的报文在用户主机之间（无需通过中间服务器直接发送）</p>
+<p><br></p>
+<p>P2P
+体系结构的最引人入胜的特性之一是它们的<strong>自扩展性</strong>。</p>
+<p>例如，在一个 P2P
+文件共享应用中，尽管每个对等方都由于请求文件产生工作负载，但每个对等方通过向其他对等方分发文件也为系统增加服务能力。</p>
+<p>P2P 体系结构也是有成本效率的，
+因为它们通常不需要庞大的服务器基础设施和服务器带宽（这与具有数据中心的客户—服务器设计形成鲜明对比）。</p>
+<p>然而，末来 P2P
+应用由于高度非集中式结构，面临安全性、性能和可靠性等挑战。</p>

+<h2 id="进程通信">2.1.2 进程通信</h2>
+<p>用操作系统的术语来说，进行通信的实际上是<strong>进程</strong>而不是程序。</p>
+<p>一个进程可以被认为是运行在端系统中的一个程序。</p>
+<p>当多个进程运行在相同的端系统上时，它们使用进程间通信机制相互通信</p>
+<p>此时进程间通信的规则由端系统上的操作系统决定，操作系统不同，通信规则可能不同</p>
+<p>而这不是我们的关注点，本书&amp;笔记仅考虑运行在不同端系统上的进程的通信。</p>
+<p>在两个不同端系统的进程，通过跨越计算机网络 交换<strong>报文</strong>
+而相互通信。</p>
+<p>发送进程生成并向网络中发送报文，接收进程接收这些报文并可能通过回送报文进行响应。</p>
+<h3 id="客户与服务器进程">1. 客户与服务器进程</h3>
+<p>网络应用程序由成对的进程组成，这些进程通过网络相互发送报文。</p>
+<p>例如，在 Web 应用程序中，一个客户浏览器进程与一台 Web
+服务器进程交换报文。</p>
+<p>在一个 P2P
+文件共享系统中，文件从一个对等方中的进程传输到另一个对等方中的进程。</p>
+<p>对每对通信进程，我们通常将这两个进程之一标识为客户，而另一个进程标识为服务器
+。</p>
+<p>对于 Web 而言，浏览器是一个客户进程，Web 服务器是一台服务器进程。</p>
+<p>对于 P2P
+文件共享，下载文件的对等方标识为客户，上载文件的对等方标识为服务器。</p>
+<p>不难发现，在 P2P
+文件共享的某些应用中，一个进程能够既是客户又是服务器。</p>
+<p>在 P2P 文件共享系统中，一个进程的确既能上载文件又能下载文件。</p>
+<p>无论如何，在任何给定的「一对进程之间的通信会话」场景中，</p>
+<p>我们仍能将一个进程标识为客户，另一个进程标识为服务器。</p>
+<p><br></p>
+<p>一般地，我们定义客户和服务器进程如下：</p>
+<blockquote>
+<p>在一对进程之间的通信会话场景中，发起通信（即在该会话开始时发起与其他进程的联系）的进程被标识为<strong>客户</strong>，在会话开始时等待联系的进程是<strong>服务器</strong>。</p>
+</blockquote>
+<ul>
+<li><p>在 Web 中一个浏览器进程向一台 Web 服务器进程发起联系</p>
+<p>则该浏览器进程是客户，Web 服务器进程是进程。</p></li>
+<li><p>在 P2P 文件共享中，当对等方 A 请求对等方 B
+发送一个特定的文件时，</p>
+<p>在这个特定的通信会话中对等方 A 是客户，而对等方 B 是服务器。</p></li>
+</ul>
+<p>在不致混淆的情况下，我们有时也是用属于“应用程序的客户端和服务器端”。</p>
+<h3 id="进程与计算机网络之间的接口">2. 进程与计算机网络之间的接口</h3>
+<p>如上所述，多数应用程序是由通信进程对组成，每对中的两个进程相互发送报文。</p>
+<p>从一个进程向另一个进程发送的报文必须通过下面的网络。</p>
+<p>进程通过一个称为<strong>套接字</strong>的软件接口向网络发送报文和从网络接受报文。</p>
+<p>打个比方，进程是一座房子，则套接字就是它的门。（注意，套接字是软件接口）</p>
+<p>当一个进程想向位于另一台主机上的另一个进程发送报文时，它会把要发的报文推出该“门”。</p>
+<p>该发送进程假定该门到另外一侧之间有运输的基础设施，该设施将把报文传送到目的进程的门口。</p>
+<p>一旦该报文抵达目的主机，它通过接受进程的“门”传递，然后接收进程对该报文进行处理。</p>
+<p><img src="../../../Documents/OI/学术/文章初稿及辅助文件/博客图片文件备份/IMG_0001.jpg" style="zoom: 33%;" /></p>
+<p>上图显示了两个经过因特网通信的进程之间的套接字通信（假定由该进程使用的下面运输层协议是
+TCP 协议）</p>
+<p>如图所示，套接字是同一台主机内应用层与运输层之间的接口，该套接字是建立网络应用程序的可编程接口。</p>
+<p>因此套接字也称为应用程序与网络之间的<strong>应用程序编程接口</strong>（API）</p>
+<p>应用程序开发者可以控制套接字在应用层端的一切，但是对该套接字的运输层端几乎没有控制权</p>
+<p>应用程序开发者对于运输层的控制仅限于：</p>
+<p>①选择运输层协议 ②设定几个运输层参数，如最大缓存和最大报文长度等</p>

+<p>这几天玩了玩《尼尔：机械纪元》，据说这是一部很感人的作品</p>
+<p>感觉这游戏是我玩过的游戏中配乐做的最好的，特别是一开始那个废墟都市的配乐，特别好听。</p>
+<p>一周目结束，感觉还是比较感人的。理性的说，其实一周目和二周目的故事比较老套，不过整体还是很好的。</p>
+<p>三周目还没完全玩完，不过还是很期待的，虽说已经看过解读的视频了（所以我才会坚持玩到三周目）</p>
+<p>对于所谓的E结局，我认为只是制作组为了让大家不留下某种遗憾才制作的</p>
+<p>真正的结局，我倾向于C结局，这才是属于那个世界真正的结局。</p>
+<p>可是，现在的感受真的和以前不一样了。</p>
+<p><br></p>
+<p>不得不说，当时看末日三问的时候，看到最后特别感动，有史以来第一次真正的“热泪盈眶”</p>
+<p>到现在我一直认为那是一部神剧。那时候初三，看完又正好碰上了2021年寒假，某种意义上，我很幸运。</p>
+<p>这里就不多提了，只知道那时候是最疯狂的时候。后来有朋友提起，说我当时怎么突然觉悟了</p>
+<p>也许他们不会理解，毕竟这是独属于我自己的感受。</p>
+<p><br></p>
+<center>
+我在写什么啊。
+</center>
+<p><br></p>
+<p>我不知道这篇文章写了有什么意义，但是我还是愿意记录下来，起码是一次情感抒发</p>
+<p>也许未来会有正确的人来阅读这篇文章。我不希望是一个随意的人来看这篇文章。</p>
+<p>之前玩《赛博朋克2077》，即便是隐藏结局，也有这样的选择：</p>
+<p>是告别这个世界，称为永生的 AI，还是选择仅剩六个月的人生。</p>
+<p>如果永生，那我存在的意义是什么呢？我没有找到，或者说根本没有意义</p>
+<p>人为什么要活着？也许就是为了体会活着，和所爱之人度过一生，然后变成尘埃，再也没有人记得你。</p>
+<p>所以我选择了继续活着，尽管只有短暂的六个月。</p>
+<p><br></p>
+<p>比起中了大奖，我更觉得自己才是幸运儿，我能在这样的年龄体会到这么多的事。</p>
+<p>我知道，我做了正确的决定。尽管我改变不了平凡，但也许，我可以让我的人生过得不平凡一些。</p>
+<p>人不能只看自己失去了什么，要多看看自己还有什么。</p>
+<p>虽然我无缘NOIP以上的赛事，但是，也许这就是命中注定。</p>
+<p>我不愿意像其他人一样，一边写着文化课学习多快乐，一边怀念竞赛的时光</p>
+<p>我也不会固执的认为，自己还是一个OIer，不会退役，不会告别竞赛。</p>
+<p>哎，怎么说呢，我也不知道怎么解释。这或许是我探索的必经之路？</p>

+<p>多项式除法是代数中的一种算法，可以快速手算出一个同次或低次的多项式去除另一个多项式的结果。</p>
+<p>事实上，小学学的竖式除法就是该算法在 <span class="math inline">\(x =

+<p><br></p>
+<p><strong>例</strong>：考虑计算 <span class="math display">\[

+\]</span> <strong>解</strong>：</p>
+<ol type="1">
+<li><p>首先把分子和分母均以降幂排列，缺项补零 <span
+class="math display">\[
+\frac{x^3-12 x^2+0 x-42}{x-3}

+                <h1 id="lsof-查看端口占用">lsof 查看端口占用</h1>
+<p><code>lsof</code> 是一个 shell 指令，用于列出当前系统打开的文件。</p>
+<p><code>lsof</code> 查看端口占用的语法格式如下：</p>
+<pre class="line-numbers language-bash" data-language="bash"><code class="language-bash"><span class="token function">lsof</span> -i:<span class="token punctuation">[</span>端口号<span class="token punctuation">]</span><span aria-hidden="true" class="line-numbers-rows"><span></span></span></code></pre>
+<p>在 Linux 上需要 root 权限，而 MacOS 上不需要。</p>
+<p>例：查看电脑 4000 端口的占用情况：</p>
+<pre class="line-numbers language-none"><code class="language-none">% lsof -i:4000
+COMMAND   PID USER   FD   TYPE             DEVICE SIZE&#x2F;OFF NODE NAME
+node    64950  qry   42u  IPv6 0x71ca5fa9e8b96e4d      0t0  TCP *:terabase (LISTEN)<span aria-hidden="true" class="line-numbers-rows"><span></span><span></span><span></span></span></code></pre>
+<p>可以发现 4000 端口已经被 nodejs
+服务占用（其实是我博客的本地调试端口）</p>
+<p>输出信息的意义如下：</p>
+<p><img src="https://raw.githubusercontent.com/q779/blog-img/main/img/202301231936446.png" style="zoom:30%;" /></p>
+<p>其他 lsof 的命令如下：</p>
+<pre class="line-numbers language-bash" data-language="bash"><code class="language-bash"><span class="token function">lsof</span> -i:8080        <span class="token comment"># 查看 8080 端口的占用</span>
+<span class="token function">lsof</span> abc.txt        <span class="token comment"># 显示开启文件 abc.txt 的进程</span>
+<span class="token function">lsof</span> -c abc         <span class="token comment"># 显示 abc 进程现在打开的文件</span>
+<span class="token function">lsof</span> -c -p <span class="token number">1234</span>     <span class="token comment"># 列出进程号为 1234 的进程所打开的文件</span>
+<span class="token function">lsof</span> -g gid         <span class="token comment"># 显示归属 gid 的进程情况</span>
+<span class="token function">lsof</span> +d /usr/local/ <span class="token comment"># 显示目录下被进程开启的文件，</span>
+<span class="token function">lsof</span> +D /usr/local/ <span class="token comment"># 同上，但是会搜索所有子文件夹内的文件</span>
+<span class="token function">lsof</span> -d <span class="token number">4</span>           <span class="token comment"># 显示使用 FD 为 4 的进程</span>
+<span class="token function">lsof</span> -i -U          <span class="token comment"># 显示所有打开的端口和 UNIX domain 文件</span><span aria-hidden="true" class="line-numbers-rows"><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span><span></span></span></code></pre>
+<p>在查到端口占用的进程后，如果你要杀掉对应的进程，可以用以下指令</p>
+<pre class="line-numbers language-bash" data-language="bash"><code class="language-bash"><span class="token function">kill</span> -9 <span class="token punctuation">[</span>PID<span class="token punctuation">]</span><span aria-hidden="true" class="line-numbers-rows"><span></span></span></code></pre>

+弹珠游戏（2021 CoE-I C）</a></p>
+<blockquote>
+<p><strong>题意</strong>：</p>
+<p><span class="math inline">\(\operatorname{Alice}\)</span>
+对弹珠游戏已经有些厌烦了，她经常在电脑上玩这个游戏。她之所以感到厌烦是因为在这个游戏上她已经是专家级别，她总是能够和电脑打成平手。<span
+class="math inline">\(\operatorname{Bob}\)</span> 为 <span
+class="math inline">\(\operatorname{Alice}\)</span>
+创造了一款新的电脑游戏。以下是这款两人电脑游戏的规则：</p>
+<p>（1）游戏在如下图所示的菱形棋盘上进行；</p>
+<p><img
+src="https://raw.githubusercontent.com/q779/blog-img/main/img/202301232216438.png" /></p>
+<p>（2）两名玩家轮流放置弹珠，可以在横向、纵向、<span
+class="math inline">\(45\)</span> 度斜线、<span
+class="math inline">\(135\)</span>
+度斜线方向未放置弹珠的位置<strong>连续放置 <span
+class="math inline">\(1\)</span> 至 <span
+class="math inline">\(3\)</span>
+颗弹珠</strong>，玩家在可以放置弹珠的情况下，必须至少放置 <span
+class="math inline">\(1\)</span>
+颗弹珠。以下是合法的单次放置操作的示例（黑色圆点表示放置了弹珠，白色圆点表示未放置弹珠，进行该次操作前棋盘为空）：</p>
+<p><img
+src="https://raw.githubusercontent.com/q779/blog-img/main/img/202301232216314.png" /></p>
+<p>以下是非法的单次放置操作的示例（黑色圆点表示放置了弹珠，白色圆点表示未放置弹珠，进行该次操作前棋盘为空）：</p>
+<p><img
+src="https://raw.githubusercontent.com/q779/blog-img/main/img/202301232216498.png" /></p>
+<p>非法原因的解释：（<span
+class="math inline">\(a\)</span>）三颗弹珠不在同一条斜线（或者垂直线）上；（<span
+class="math inline">\(b\)</span>）两颗弹珠之间相隔一个空位；（<span
+class="math inline">\(c\)</span>）三颗弹珠不在同一条斜线上；（<span
+class="math inline">\(d\)</span>）三颗弹珠不在同一条斜线（或者垂直线）上；（<span
+class="math inline">\(e\)</span>）一次性放置了 <span
+class="math inline">\(4\)</span> 颗弹珠；（<span
+class="math inline">\(f\)</span>）三颗弹珠不在同一条水平线（或者垂直线、或者斜线）上。</p>
+<p>（3）如果某位玩家无法再继续放置弹珠，则该名玩家输掉游戏，另外一名玩家获胜。</p>
+<p><span class="math inline">\(\operatorname{Alice}\)</span>
+总是第一个进行游戏，而且经常是和 <span
+class="math inline">\(\operatorname{Bob}\)</span> 玩这个游戏，<span
+class="math inline">\(\operatorname{Bob}\)</span>
+在进行若干游戏操作后可能会离开，将游戏交由电脑代理，电脑总是按照最优策略放置弹珠。
+给定 <span class="math inline">\(\operatorname{Bob}\)</span>
+离开后的游戏状态，你的任务是确定 <span
+class="math inline">\(\operatorname{Alice}\)</span>
+是否可能在对阵电脑时获得胜利。</p>
+<p><strong>输入格式</strong>：</p>
+<p>输入第一行包含一个整数 <span
+class="math inline">\(T\)</span>，表示测试数据的组数。接着是一个空行。再接下来是
+<span class="math inline">\(T\)</span>
+组表示棋盘状态的数据，每组数据由七行字符构成，表示 <span
+class="math inline">\(\operatorname{Bob}\)</span>
+离开后的游戏状态，<code>*</code>
+表示该位置已经放置了弹珠，<code>.</code>
+表示该位置未放置弹珠。相邻两组测试数据之间有一个空行。</p>
+<p><strong>输出格式</strong>：</p>
+<p>对于每组测试数据，如果 <span
+class="math inline">\(\operatorname{Alice}\)</span> 能够获胜，输出
+<code>Possible.</code>，否则输出 <code>Impossible.</code>。</p>
+<p><strong>数据范围</strong>：</p>
+<p>对于 <span class="math inline">\(100\%\)</span> 的数据，<span
+class="math inline">\(0 \lt T \leq 10^6\)</span>。</p>
+</blockquote>
+<p>首先把棋盘转 <span class="math inline">\(45^{\circ}\)</span>
+，便于处理。</p>
+<p>一眼博弈论，注意到棋盘大小很小，考虑记忆化搜索处理</p>
+<p>设 <span class="math inline">\(f_S\)</span> 表示状态为 <span
+class="math inline">\(S\)</span>
+时是否先手必胜，转移枚举空位暴力填。</p>
+<p>由于往左下填和往右上填本质是一致的，所以我们只需要枚举「左下」「下」「右下」「右」即可。</p>
+<p>小细节，填三个可以从填两个的再补上一个，写的时候直接或一下就好了。</p>
+<p>时间复杂度 <span class="math inline">\(\mathcal{O}(2^{16} +

+<p>题目链接：<a target="_blank" rel="noopener" href="https://www.luogu.com.cn/problem/P2151">P2151
+[SDOI2009] HH去散步</a></p>
+<blockquote>
+<p><strong>题意</strong>：</p>
+<p>HH有个一成不变的习惯，喜欢饭后百步走。所谓百步走，就是散步，就是在一定的时间
+内，走过一定的距离。
+但是同时HH又是个喜欢变化的人，所以他不会立刻沿着刚刚走来的路走回。
+又因为HH是个喜欢变化的人，所以他每天走过的路径都不完全一样，他想知道他究竟有多
+少种散步的方法。</p>
+<p>现在给你学校的地图（假设每条路的长度都是一样的都是 <span
+class="math inline">\(1\)</span> ），问长度为 <span
+class="math inline">\(t\)</span> ，从给定地点 <span
+class="math inline">\(A\)</span> 走到给定地点 <span
+class="math inline">\(B\)</span> 共有多少条符合条件的路径</p>
+<p><strong>输入格式</strong>：</p>
+<p>第一行：五个整数 <span class="math inline">\(n,m,t,A,B\)</span>。其中
+<span class="math inline">\(n\)</span> 表示学校里的路口的个数， <span
+class="math inline">\(m\)</span> 表示学校里的路的条数，<span
+class="math inline">\(t\)</span> 表示HH想要散步的距离，<span
+class="math inline">\(A\)</span> 表示散步的出发点，而 <span
+class="math inline">\(B\)</span> 则表示散步的终点。</p>
+<p>接下来 <span class="math inline">\(m\)</span> 行，每行一组 <span
+class="math inline">\(A_i,B_i\)</span> ，表示从路口 <span
+class="math inline">\(A_i\)</span> 到路口 <span
+class="math inline">\(B_i\)</span> 有一条路。数据保证 <span
+class="math inline">\(A_i \ne B_i\)</span>
+，但不保证任意两个路口之间至多只有一条路相连接。 路口编号从 <span
+class="math inline">\(0\)</span> 到 <span
+class="math inline">\(n-1\)</span> 。
+同一行内所有数据均由一个空格隔开，行首行尾没有多余空格。没有多余空行。
+答案模 <span class="math inline">\(45989\)</span> 。</p>
+<p><strong>输出格式</strong>：</p>
+<p>一行，表示答案。</p>
+<p><strong>数据范围</strong>：</p>
+<p><span class="math inline">\(n \le 50,~m \le 60,~t \le 2^{30},~0 \le
+A,B\)</span></p>
+</blockquote>
+<p>设 <span class="math inline">\(f_{i,j}\)</span> 表示不考虑限制走了
+<span class="math inline">\(i\)</span> 步，到达 <span
+class="math inline">\(j\)</span> 的方案数，则 <span
+class="math display">\[
+f_{i,j} = \sum_{k \in S(j)} f_{i-1,k} \times s(k,j)
+\]</span> 其中 <span class="math inline">\(S(j)\)</span> 为能到达 <span
+class="math inline">\(j\)</span> 的节点的集合，<span
+class="math inline">\(s(k,j)\)</span> 表示重边数。</p>
+<p>加入限制以后，这个 <span class="math inline">\(S\)</span>
+就不好用了，考虑重新定义它。</p>
+<p>定义 <span class="math inline">\(S(j)\)</span> 为终点为 <span
+class="math inline">\(j\)</span>
+的<strong>边</strong>的集合（不包括反向边）</p>
+<p>此时 <span class="math inline">\(f_{i,j}\)</span> 表示走了 <span
+class="math inline">\(i\)</span> 步，到达 <span
+class="math inline">\(j\)</span> 的方案数，式子形式基本不变 <span
+class="math display">\[
+f_{i,j} = \sum_{k \in S(j)} f_{i-1,k} \times s(k)
+\]</span> 然后就是简单的矩阵快速幂，注意顺序不要反了，<span
+class="math inline">\(M_{i,j}\)</span> 表示 <span
+class="math inline">\(i \to j\)</span> 时的转移系数。</p>
+<p>时间复杂度 <span class="math inline">\(\mathcal{O}(8m^3\log
+t)\)</span></p>

+在概率论和统计学中，一个离散性随机变量的期望值（或数学期望，亦简称期望）是试验中每次可能的结果乘以其结果概率的总和。
+期望值更像是随机试验在同样的机会下重复多次，所有那些可能状态平均的结果，便基本上等同“期望值”所期望的数。

-在概率论和统计学中，一个离散性随机变量的期望值（或数学期望，亦简称期望）是试验中每次可能的结果乘以其结果概率的总和。
-期望值更像是随机试验在同样的机会下重复多次，所有那些可能状态平均的结果，便基本上等同“期望值”所期望的数。

+妈妈就让他隔离在他的房间，然后拿出了各种什么东西消杀病菌啥的。

-总结：脑子会变笨，所以要吃点糖类。
-大脑只能利用葡萄糖而不能利用脂肪酸供能，主要原因是脂肪酸分子较大不能透过血脑屏障。
-因此只吃脂肪不吃糖的人来说，身体会通过另一过程（即酮体生成途径，如图）生成酮体

+总结：脑子会变笨，所以要吃点糖类。
+大脑只能利用葡萄糖而不能利用脂肪酸供能，主要原因是脂肪酸分子较大不能透过血脑屏障。
+因此只吃脂肪不吃糖的人来说，身体会通过另一过程（即酮体生成途径，如图）生成酮体

+一、葡萄糖转化为脂肪
+葡萄糖多了会转化成脂肪，主要是由于血糖的升高引起胰岛素的分泌，

-总结：脑子会变笨，所以要吃点糖类。
-大脑只能利用葡萄糖而不能利用脂肪酸供能，主要原因是脂肪酸分子较大不能透过血脑屏障。
-因此只吃脂肪不吃糖的人来说，身体会通过另一过程（即酮体生成途径，如图）生成酮体

+                                    「生物」人为什么不能只吃脂肪而不吃糖类？
+总结：脑子会变笨，所以要吃点糖类。
+大脑只能利用葡萄糖而不能利用脂肪酸供能，主要原因是脂肪酸分子较大不能透过血脑屏障。
+因此只吃脂肪不吃糖的人来说，身体会通过另一过程（即酮体生成途径，如图）生成酮体

-这个域既可以是一个邻域，又可以是整个函数域（这时极值称为最值、

-问：（来自link）
-定义在 \(\mathbb{R}\) 上的连续函数在
-\(x=a\) 处不可导，那么它在 \(a\) 处可以有切线吗？
-解：
-需要区分的是，切线是几何概念，导数是代数概念
-「函数在 \(x=a\) 处可

+在数学中，极值是极大值与极小值的统称，意指在一个域上函数取得最大值或最小值的点的函数值。
+而「使函数取得极值的点」的横坐标被称作极值点。（注意极值点是一个数，不是一个点）
+这个域既可以是一个邻域，又可以是整个函数域（这时极值称为最值、

-常用步骤：
-利用导数的几何意义求参数时，常根据以下关系列方程：
-
-函数在切点处的导数值等于切线的斜率
-切点在切线上
-切点在曲线上
-题目所给的其他条件
-
-最后通过解方程(组)得到参数的值。

-kd-tree 是一种可以高效处理 \(k\)
-维空间的数据结构
-在算法竞赛类的题目中一般有 \(k=2\)
-还有个比较有趣的结论，当 \(k=1\)
-时其实它就是一棵线段树

-利用导数求切线的斜率是一种非常有效的方法，它适用于任何可导函数。
-求曲线的切线方程时，一定要注意已知点是否为切点。
-若切点没有给出,一般是先把切点坐标设出来，并求出切点坐标，再求切线方程。

+今天看到一个新闻，大概是：我国自 2026 年起，水银温度计全面禁产

+这时候就产生了一种认知偏差，我不希望别人改变我

+今天看到一个新闻，大概是：我国自 2026 年起，水银温度计全面禁产

+而且我一直都是用水银温度计的，因为电子测温计公认的不准确
+这时候就产生了一种认知偏差，我不希望别人改变我

-总结：脑子会变笨，所以要吃点糖类。
-大脑只能利用葡萄糖而不能利用脂肪酸供能，主要原因是脂肪酸分子较大不能透过血脑屏障。
-因此只吃脂肪不吃糖的人来说，身体会通过另一过程（即酮体生成途径，如图）生成酮体

+总结：脑子会变笨，所以要吃点糖类。
+大脑只能利用葡萄糖而不能利用脂肪酸供能，主要原因是脂肪酸分子较大不能透过血脑屏障。
+因此只吃脂肪不吃糖的人来说，身体会通过另一过程（即酮体生成途径，如图）生成酮体

-常用步骤：
-利用导数的几何意义求参数时，常根据以下关系列方程：
-
-函数在切点处的导数值等于切线的斜率
-切点在切线上
-切点在曲线上
-题目所给的其他条件
-
-最后通过解方程(组)得到参数的值。

-均值不等式
-引理1：若 \(a\ge 0,b\ge

-利用导数求切线的斜率是一种非常有效的方法，它适用于任何可导函数。
-求曲线的切线方程时，一定要注意已知点是否为切点。
-若切点没有给出,一般是先把切点坐标设出来，并求出切点坐标，再求切线方程。

+还有很多证明方法，等我学了再写 qwq
 
-一、珂朵莉树来源
-珂朵莉树，原名老司机树（Old Driver
-Tree），在某场CF比赛中提出
-因为题目背景是《末日时在做什么？有没有空？可以来拯救吗？》中的珂朵莉，所以就叫珂朵莉树了
+均值不等式
+引理1：若 \(a\ge 0,b\ge
+0\) ，则 \((a+b)^n\ge
+a^n+na^{n-1}b,n\in \Z_+\)

-状压dp（状态压缩动态规划）是一种dp。（废话）
-状压dp的核心就是把若干状态压缩为一个整数
-通常要压缩的元素个数不超过 \(15\)

-最长不下降子序列问题
+                                求曲线的切线方程
+利用导数求切线的斜率是一种非常有效的方法，它适用于任何可导函数。
+求曲线的切线方程时，一定要注意已知点是否为切点。
+若切点没有给出,一般是先把切点坐标设出来，并求出切点坐标，再求切线方程。
 
-题意：
-给定正整数序列 \(x_1 \ldots,
-x_n\)。
+常用步骤
 
-计算其最长不下降子序列的长度 \(s\)。
-如果每个元素只允许使用一次，计算从给定
+求解以曲线上的点

-想必大家都听说过快速幂
-那快速乘是个什么东西呢？
-考虑取模操作a*b%p，1^10 ≤ a,b,p ≤ 2^10
-可以发现在 long long情况下，我们直接取模会溢出
-那么怎么办呢？

+今天看到一个新闻，大概是：我国自 2026 年起，水银温度计全面禁产
+首先我感到很惊讶，这么好用的东西为什么要禁产呢？

+这时候就产生了一种认知偏差，我不希望别人改变我

+2022年12月14日
+当我在打植物大战僵尸时，爸爸说他抗原检测阳性了。
+妈妈就让他隔离在他的房间，然后拿出了各种什么东西消杀病菌啥的。
+比如说放了什么艾灸的东西在那熏。目前感觉还行，就是被熏的鼻子干还有点呛...

+<p>Problem Link: <a target="_blank" rel="noopener" href="https://www.luogu.com.cn/problem/P2656">P2656
+采蘑菇</a></p>
+<blockquote>
+<p><strong>Meaning</strong>:</p>
+<p>q779 and cxy are going to a forest to pick mushrooms.</p>
+<p>There are <span class="math inline">\(N\)</span> bushes in the forest
+and <span class="math inline">\(M\)</span> trails, each of which is a
+one-way path connecting two bushes with a certain number of mushrooms.
+q779 and cxy can pick all the mushrooms on a path by passing it once.
+Since the forest is a magically fertile land, after the mushrooms on a
+path are picked, new mushrooms will grow, multiplying the number of
+mushrooms by the "recovery factor" of the path <span
+class="math inline">\(c\)</span> and rounding down.</p>
+<p>For example, if there are <span class="math inline">\(4\)</span>
+mushrooms on a path and the "recovery factor" of the path is <span
+class="math inline">\(c = 0.7\)</span>, then the number of mushrooms
+that can be picked from the first to the fourth time through the path is
+<span class="math inline">\(4,2,1,0\)</span> respectively.</p>
+<p>Now, q779 and cxy start from bush <span
+class="math inline">\(S\)</span> and find the maximum number of
+mushrooms they can pick.</p>
+<p><strong>Input</strong>:</p>
+<p>Two integers, <span class="math inline">\(N\)</span> and <span
+class="math inline">\(M\)</span>, in the first row.</p>
+<p>The second to <span class="math inline">\(M+1\)</span> rows, four
+numbers per row, denote the starting point, the ending point, the
+initial number of mushrooms and the recovery factor of a trail,
+respectively.</p>
+<p>In the <span class="math inline">\(M+2\)</span> th row, an integer
+<span class="math inline">\(S\)</span>.</p>
+<p><strong>Output</strong>:</p>
+<p>One integer in a row indicates the maximum number of mushrooms that
+can be picked, ensuring that the answer does not exceed <span
+class="math inline">\(2^{31}-1\)</span>.</p>
+<p><strong>Data range</strong>:</p>
+<p><span class="math inline">\(1 \le N\le 8\times 10^4,~1\le M\le
+2\times 10^5,~0\le c\le 0.8\)</span> and up to one decimal, <span
+class="math inline">\(1\le S\le N\)</span>.</p>
+</blockquote>
+<p>The first problem solution after the resurrection, <del>also a
+warm-up question</del>.</p>
+<p>Anyway, may my dream come true in NOIP.</p>
+<p>Notice that an edge can be walked an infinite number of times,</p>
+<p>then any strongly connected component can be walked until it does not
+grow mushrooms.</p>
+<p>Consider shrinking points and preprocessing the answer for each
+strongly connected component</p>
+<p>Then it becomes simple "do topo+dp on DAG"</p>
+<p>The time complexity is <span class="math inline">\(\mathcal{O}(m
+\log_{\frac{4}{5}} M)\)</span>, in short, can be passed.</p>

+<blockquote>
+<p><strong>Meaning</strong>:</p>
+<p>Given a text string <span class="math inline">\(t\)</span> and <span
+class="math inline">\(n\)</span> pattern strings <span
+class="math inline">\(s_i\)</span>, find <span class="math display">\[
+\sum_{i=1}^n\sum_{j=1}^nf(s_i + s_j)
+\]</span> <span class="math inline">\(f(s)\)</span> is defined as the
+number of occurrences of <span class="math inline">\(s\)</span> in <span
+class="math inline">\(t\)</span>, and <span class="math inline">\(s_i +
+s_j\)</span> is defined as the splice strings <span
+class="math inline">\(s_i\)</span> and <span
+class="math inline">\(s_j\)</span>.</p>
+<p><strong>Input</strong>:</p>
+<p>One line <span class="math inline">\(t\)</span>, one line <span
+class="math inline">\(n\)</span>, and the next <span
+class="math inline">\(n\)</span> line <span
+class="math inline">\(s_i\)</span>.</p>
+<p><strong>Output</strong>:</p>
+<p>Answer.</p>
+<p><strong>Data Range</strong>:</p>
+<p><span class="math inline">\(1\le |t|,\sum |s_i| \le 2\times
+10^5\)</span> .</p>
+</blockquote>
+<p>This kind of question must consider the contribution of a certain
+string.</p>
+<p>Here we consider the enumeration division point <span
+class="math inline">\(x\)</span>. Denote the point before as <span
+class="math inline">\(s_i\)</span> and the point after as <span
+class="math inline">\(s_j\)</span></p>
+<p>Count the number of <span class="math inline">\(f(x),g(x+1)\)</span>
+before and after each <span class="math inline">\(x\)</span>.</p>
+<p>How do we count them? Notice that <span
+class="math inline">\(f(x)\)</span> is actually how many known
+substrings are in the suffix of <span class="math inline">\(t_{1 \cdots
+x}\)</span> and <span class="math inline">\(g(x)\)</span> is the reverse
+of <span class="math inline">\(f(x)\)</span> .</p>
+<p>This is something that can be messed with using AC automata. That is,
+build the AC automaton directly on the pattern string and run <span
+class="math inline">\(t\)</span> through it.</p>
+<p>Consider that the fail pointer points to the longest suffix from the
+root to the current string, and then the request is equivalent to the
+number of suffixes for the pattern string.</p>
+<p>As we know from the AC automaton's code, this is simply a matter of
+summing over the fail tree.</p>
+<p>Time Complexity is <span class="math inline">\(\mathcal{O}(\sum |s_i|
+\times |\Sigma|)\)</span></p>

Notice that <spanclass="math inline">\(f(x)\)</span> is actually how many knownsubstrings are in the suffix of <span class="math inline">\(t_{1 \cdotsx}\)</span> and <span class="math inline">\(g(x)\)</span> is the reverseof <span class="math inline">\(f(x)\)</span> .</p><p>This is something that can be messed with using AC automata. That is,build the AC automaton directly on the pattern string and run <spanclass="math inline">\(t\)</span> through it.</p><p>Consider that the fail pointer points to the longest suffix from theroot to the current string, and then the request is equivalent to thenumber of suffixes for the pattern string.</p><p>As we know from the AC automaton's code, this is simply a matter ofsumming over the

href="https://www.luogu.com.cn/problem/P2656">P2656采蘑菇</a></p><blockquote><p><strong>Meaning</strong>:</p><p>q779 and cxy are going to a forest to pick mushrooms.</p><p>There are <span class="math inline">\(N\)</span> bushes in the forestand <span class="math inline">\(M\)</span> trails, each of which is aone-way path connecting two bushes with a certain number of mushrooms.q779 and cxy can pick all the mushrooms on a path by passing it once.Since the forest is a magically fertile land, after the mushrooms on apath are picked, new mushrooms will grow, multiplying the number ofmushrooms by the "recovery factor" of the path <spanclass="math inline">\(c\)</span> and rounding down.</p><p>For example, if there are <span class="math inline">\(4\)</span>mushrooms on a path and the "recovery factor" of the path is <spanclass="math inline">\(c = 0.7\)</span>, then the number of mushroomsthat can be picked from the first to the fourth time through the path is<span class="math inline">\(4,2,1,0\)</span> respectively.</p><p>Now, q779 and cxy start from bush <spanclass="math inline">\(S\)</span> and find the maximum number ofmushrooms they can pick.</p><p><strong>Input</strong>:</p><p>Two integers, <span class="math inline">\(N\)</span> and <spanclass="math inline">\(M\)</span>, in the first row.</p><p>The second to <span class="math inline">\(M+1\)</span> rows, fournumbers per row, denote the starting point, the ending point, theinitial number of mushrooms and the recovery factor of a trail,respectively.</p><p>In the <span class="math inline">\(M+2\)</span> th row, an integer<span class="math inline">\(S\)</span>.</p><p><strong>Output</strong>:</p><p>One integer in a row indicates the maximum number of mushrooms thatcan be picked, ensuring that the answer does not exceed <spanclass="math inline">\(2^{31}-1\)</span>.</p><p><strong>Data range</strong>:</p><p><span class="math inline">\(1 \le N\le 8\times 10^4,~1\le M\le2\times 10^5,~0\le c\le 0.8\)</span> and up to one decimal, <spanclass="math inline">\(1\le S\le N\)</span>.</p></blockquote><p>The first problem solution after the resurrection, <del>also awarm-up question</del>.</p><p>Anyway, may my dream come true in NOIP.</p><p>Notice that an edge can be walked an infinite number of times,</p><p>then any strongly connected component can be walked until it does notgrow mushrooms.</p><p>Consider shrinking points and preprocessing the answer for eachstrongly connected component</p><p>Then it becomes simple "do topo+dp on DAG"</p><p>The time complexity is <span class="math inline">\(\mathcal{O}(m\log_{\frac{4}{5}} M)\)</span>, in short, can be passed.</p><p>code:</p><pre class="line-numbers language-cpp" data-language="cpp"><code

-总结：脑子会变笨，所以要吃点糖类。
-大脑只能利用葡萄糖而不能利用脂肪酸供能，主要原因是脂肪酸分子较大不能透过血脑屏障。
-因此只吃脂肪不吃糖的人来说，身体会通过另一过程（即酮体生成途径，如图）生成酮体

+总结：脑子会变笨，所以要吃点糖类。
+大脑只能利用葡萄糖而不能利用脂肪酸供能，主要原因是脂肪酸分子较大不能透过血脑屏障。

-对于给定的一段正整数序列，逆序对就是序列中 \(a_i&gt;a_j\) 且 \(i&lt;j\) 的有序对
-
-二、怎么求逆序对
-1.归并排序解法
-归并排序可以很好的解决逆序对问题
-我们只需要计算跨越分

-一、珂朵莉树来源
-珂朵莉树，原名老司机树（Old Driver

-因为题目背景是《末日时在做什么？有没有空？可以来拯救吗？》中的珂朵莉，所以就叫珂朵莉树了

-                                模拟退火 学习笔记
-模拟退火挺没有正确性的。真的是个玄学。
-基本思想：如果新的状态的解更优则修改答案，否则以一定的概率接受新状态，这个概率为
-\(\exp(\frac{-\Delta E}{t})\) 。

HH去散步</a></p><blockquote><p><strong>题意</strong>：</p><p>HH有个一成不变的习惯，喜欢饭后百步走。所谓百步走，就是散步，就是在一定的时间内，走过一定的距离。但是同时HH又是个喜欢变化的人，所以他不会立刻沿着刚刚走来的路走回。又因为HH是个喜欢变化的人，所以他每天走过的路径都不完全一样，他想知道他究竟有多少种散步的方法。</p><p>现在给你学校的地图（假设每条路的长度都是一样的都是 <spanclass="math inline">\(1\)</span> ），问长度为 <spanclass="math inline">\(t\)</span> ，从给定地点 <spanclass="math inline">\(A\)</span> 走到给定地点 <spanclass="math inline">\(B\)</span> 共有多少条符合条件的路径</p><p><strong>输入格式</strong>：</p><p>第一行：五个整数 <span class="math inline">\(n,m,t,A,B\)</span>。其中<span class="math inline">\(n\)</span> 表示学校里的路口的个数， <spanclass="math inline">\(m\)</span> 表示学校里的路的条数，<spanclass="math inline">\(t\)</span> 表示HH想要散步的距离，<spanclass="math inline">\(A\)</span> 表示散步的出发点，而 <spanclass="math inline">\(B\)</span> 则表示散步的终点。</p><p>接下来 <span class="math inline">\(m\)</span> 行，每行一组 <spanclass="math inline">\(A_i,B_i\)</span> ，表示从路口 <spanclass="math inline">\(A_i\)</span> 到路口 <spanclass="math inline">\(B_i\)</span> 有一条路。数据保证 <spanclass="math inline">\(A_i \ne B_i\)</span>，但不保证任意两个路口之间至多只有一条路相连接。 路口编号从 <spanclass="math inline">\(0\)</span> 到 <spanclass="math inline">\(n-1\)</span> 。同一行内所有数据均由一个空格隔开，行首行尾没有多余空格。没有多余空行。答案模 <span class="math inline">\(45989\)</span> 。</p><p><strong>输出格式</strong>：</p><p>一行，表示答案。</p><p><strong>数据范围</strong>：</p><p><span class="math inline">\(n \le 50,~m \le 60,~t \le 2^{30},~0 \leA,B\)</span></p></blockquote><p>设 <span class="math inline">\(f_{i,j}\)</span> 表示不考虑限制走了<span class="math inline">\(i\)</span> 步，到达 <spanclass="math inline">\(j\)</span> 的方案数，则 <spanclass="math display">\[f_{i,j} = \sum_{k \in S(j)} f_{i-1,k} \times s(k,j)\]</span> 其中 <span class="math inline">\(S(j)\)</span> 为能到达 <spanclass="math inline">\(j\)</span> 的节点的集合，<spanclass="math inline">\(s(k,j)\)</span> 表示重边数。</p><p>加入限制以后，这个 <span class="math inline">\(S\)</span>就不好用了，考虑重新定义它。</p><p>定义 <span class="math inline">\(S(j)\)</span> 为终点为 <spanclass="math inline">\(j\)</span>的<strong>边</strong>的集合（不包括反向边）</p><p>此时 <span class="math inline">\(f_{i,j}\)</span> 表示走了 <spanclass="math inline">\(i\)</span> 步，到达 <spanclass="math inline">\(j\)</span> 的方案数，式子形式基本不变 <spanclass="math display">\[f_{i,j} = \sum_{k \in S(j)} f_{i-1,k} \times s(k)\]</span> 然后就是简单的矩阵快速幂，注意顺序不要反了，<spanclass="math inline">\(M_{i,j}\)</span> 表示 <spanclass="math inline">\(i \to j\)</span> 时的转移系数。</p><p>时间复杂度 <span class="math inline">\(\mathcal{O}(8m^3\logt)\)</span></p><p>代码：</p><pre class="line-numbers language-cpp" data-language="cpp"><code class="language-cpp"><span

C）</a></p><blockquote><p><strong>题意</strong>：</p><p><span class="math inline">\(\operatorname{Alice}\)</span>对弹珠游戏已经有些厌烦了，她经常在电脑上玩这个游戏。她之所以感到厌烦是因为在这个游戏上她已经是专家级别，她总是能够和电脑打成平手。<spanclass="math inline">\(\operatorname{Bob}\)</span> 为 <spanclass="math inline">\(\operatorname{Alice}\)</span>创造了一款新的电脑游戏。以下是这款两人电脑游戏的规则：</p><p>（1）游戏在如下图所示的菱形棋盘上进行；</p><p><imgsrc="https://raw.githubusercontent.com/q779/blog-img/main/img/202301232216438.png" /></p><p>（2）两名玩家轮流放置弹珠，可以在横向、纵向、<spanclass="math inline">\(45\)</span> 度斜线、<spanclass="math inline">\(135\)</span>度斜线方向未放置弹珠的位置<strong>连续放置 <spanclass="math inline">\(1\)</span> 至 <spanclass="math inline">\(3\)</span>颗弹珠</strong>，玩家在可以放置弹珠的情况下，必须至少放置 <spanclass="math inline">\(1\)</span>颗弹珠。以下是合法的单次放置操作的示例（黑色圆点表示放置了弹珠，白色圆点表示未放置弹珠，进行该次操作前棋盘为空）：</p><p><imgsrc="https://raw.githubusercontent.com/q779/blog-img/main/img/202301232216314.png" /></p><p>以下是非法的单次放置操作的示例（黑色圆点表示放置了弹珠，白色圆点表示未放置弹珠，进行该次操作前棋盘为空）：</p><p><imgsrc="https://raw.githubusercontent.com/q779/blog-img/main/img/202301232216498.png" /></p><p>非法原因的解释：（<spanclass="math inline">\(a\)</span>）三颗弹珠不在同一条斜线（或者垂直线）上；（<spanclass="math inline">\(b\)</span>）两颗弹珠之间相隔一个空位；（<spanclass="math inline">\(c\)</span>）三颗弹珠不在同一条斜线上；（<spanclass="math inline">\(d\)</span>）三颗弹珠不在同一条斜线（或者垂直线）上；（<spanclass="math inline">\(e\)</span>）一次性放置了 <spanclass="math inline">\(4\)</span> 颗弹珠；（<spanclass="math inline">\(f\)</span>）三颗弹珠不在同一条水平线（或者垂直线、或者斜线）上。</p><p>（3）如果某位玩家无法再继续放置弹珠，则该名玩家输掉游戏，另外一名玩家获胜。</p><p><span class="math inline">\(\operatorname{Alice}\)</span>总是第一个进行游戏，而且经常是和 <spanclass="math inline">\(\operatorname{Bob}\)</span> 玩这个游戏，<spanclass="math inline">\(\operatorname{Bob}\)</span>在进行若干游戏操作后可能会离开，将游戏交由电脑代理，电脑总是按照最优策略放置弹珠。给定 <span class="math inline">\(\operatorname{Bob}\)</span>离开后的游戏状态，你的任务是确定 <spanclass="math inline">\(\operatorname{Alice}\)</span>是否可能在对阵电脑时获得胜利。</p><p><strong>输入格式</strong>：</p><p>输入第一行包含一个整数 <spanclass="math inline">\(T\)</span>，表示测试数据的组数。接着是一个空行。再接下来是<span class="math inline">\(T\)</span>组表示棋盘状态的数据，每组数据由七行字符构成，表示 <spanclass="math inline">\(\operatorname{Bob}\)</span>离开后的游戏状态，<code>*</code>表示该位置已经放置了弹珠，<code>.</code>表示该位置未放置弹珠。相邻两组测试数据之间有一个空行。</p><p><strong>输出格式</strong>：</p><p>对于每组测试数据，如果 <spanclass="math inline">\(\operatorname{Alice}\)</span> 能够获胜，输出<code>Possible.</code>，否则输出 <code>Impossible.</code>。</p><p><strong>数据范围</strong>：</p><p>对于 <span class="math inline">\(100\%\)</span> 的数据，<spanclass="math inline">\(0 \lt T \leq 10^6\)</span>。</p></blockquote><p>首先把棋盘转 <span class="math inline">\(45^{\circ}\)</span>，便于处理。</p><p>一眼博弈论，注意到棋盘大小很小，考虑记忆化搜索处理</p><p>设 <span class="math inline">\(f_S\)</span> 表示状态为 <spanclass="math inline">\(S\)</span>时是否先手必胜，转移枚举空位暴力填。</p><p>由于往左下填和往右上填本质是一致的，所以我们只需要枚举「左下」「下」「右下」「右」即可。</p><p>小细节，填三个可以从填两个的再补上一个，写的时候直接或一下就好了。</p><p>时间复杂度 <span

href="https://www.luogu.com.cn/problem/P2233">P2233[HNOI2002]公交车路线</a></p><blockquote><p><strong>题意</strong>：</p><p>在幻想郷新建的环城公路上一共有 <span class="math inline">\(8\)</span>个公交站，分别为 A、B、C、D、E、F、G、H。</p><p>公共汽车只能够在相邻的两个公交站之间运行，因此你从某一个公交站到另外一个公交站往往要换几次车，例如从公交站<span class="math inline">\(A\)</span> 到公交站 <spanclass="math inline">\(D\)</span>，你就至少需要换 <spanclass="math inline">\(3\)</span> 次车。</p><p><img src="https://raw.githubusercontent.com/q779/blog-img/main/img/202301082005890.png" style="zoom:33%;" /></p><p>不过琪露诺的方向感极其糟糕，我们知道从公交站 <spanclass="math inline">\(A\)</span> 到公交 <spanclass="math inline">\(E\)</span> 只需要换 <spanclass="math inline">\(4\)</span> 次车就可以到达，而她却总共换了 <spanclass="math inline">\(n\)</span> 次车！</p><p>注意琪露诺一旦到达公交站 <spanclass="math inline">\(E\)</span>，她不会笨到再去换车。现在希望你计算一下琪露诺有多少种可能的乘车方案。</p><p><strong>输入格式</strong>：</p><p>仅有一个正整数 <spanclass="math inline">\(n\)</span>，表示琪露诺从公交车站 A 到公交车站 E共换了 <span class="math inline">\(n\)</span> 次车。</p><p><strong>输出格式</strong>：</p><p>输出一个正整数表示方案数，由于方案数很大，请输出方案数除以 <spanclass="math inline">\(1000\)</span> 后的余数。</p><p><strong>数据范围</strong>：</p><p><span class="math inline">\(4\le n\le10^7\)</span>。</p></blockquote><p>首先从 <span class="math inline">\(E\)</span> 断环为链，因为走到<span class="math inline">\(E\)</span> 以后不会再换车。</p><p>此时的公交线路就关于 <span class="math inline">\(A\)</span>对称了，容易发现相对称的两个站点方案数是相同的。</p><p>故我们只对 <span class="math inline">\(A \sim D\)</span> 做一遍dp。设<span class="math inline">\(f_{i,j}\)</span> 表示走了 <spanclass="math inline">\(i\)</span> 步到 <spanclass="math inline">\(j\)</span> 的方案数，则有 <spanclass="math display">\[f_{i,j} = f_{i-1,j-1} + f_{i-1,j+1}\]</span> 稍微滚滚数组就好啦，时间复杂度 <spanclass="math inline">\(\mathcal{O}(n)\)</span> ，代码如下：</p><pre

Substrings</a></p><blockquote><p><strong>题意</strong>：</p><p>给定两个正整数 <span class="math inline">\(l, r\)</span> ，称整数<span class="math inline">\(x\)</span> 为好的，当且仅当 <spanclass="math inline">\(l \leq x \leq r\)</span> 。</p><p>对一个由 <span class="math inline">\(\texttt{0-9}\)</span>中数字构成的字符串，定义它的权值为这样的非空子串个数：</p><ul><li>它不以 <span class="math inline">\(\texttt{0}\)</span>开头，且将其看成数字后是好的。</li></ul><p>你需要找到一个长度为 <span class="math inline">\(n\)</span>的字符串，使得它的权值最大。</p><p>如果有多个字符串,你需要寻找字典序最小的一个。同时，字符串可以有前导零。</p><p><strong>输入格式</strong>：</p><p>三行，每行一个正整数，第一行为 <span class="math inline">\(l\)</span>，第二行为 <span class="math inline">\(r\)</span> ，第三行为 <spanclass="math inline">\(n\)</span> 。</p><p><strong>输出格式</strong>：</p><p>两行，第一行表示最大权值，第二行表示权值等于最大权值的最小大数。</p><p><strong>数据范围</strong>：</p><p><span class="math inline">\(1 \leq l,r \leq 10^{800} , 1 \leq n \leq2000\)</span> 。</p></blockquote><p>复活后的第一道黑题，有一说一难度确实很高。</p><p>首先考虑 <span class="math inline">\(l,r\)</span>相差较小的情况，可以考虑对 <span class="math inline">\([l,r]\)</span>间的所有数字建 <span class="math inline">\(\mathtt{AC}\)</span>自动机，然后在上面跑 dp 统计答案。</p><p>考虑节点 <span class="math inline">\(i\)</span> 代表的串对答案的贡献<span class="math inline">\(g_i\)</span> ，则 <spanclass="math inline">\(g_i\)</span> 为节点 <spanclass="math inline">\(i\)</span> 跳失配指针能到的点的贡献总和，即 <spanclass="math display">\[\begin{aligned}g_v \uparrow g_{\texttt{fail}_v} &amp;&amp;&amp;&amp;\big(a\uparrow b :=a \gets a + b\big)\end{aligned}\]</span> 设 <span class="math inline">\(f_{i,j}\)</span> 表示在节点<span class="math inline">\(j\)</span> 上组成 <spanclass="math inline">\(i\)</span> 位数的方案数，显然可以拿 <spanclass="math inline">\(f_{l,u} + g_v\)</span> 来更新 <spanclass="math inline">\(f_{l+1,v}\)</span> ，答案就是 <spanclass="math inline">\(\max f_{n,i}\)</span></p><p>但是这里 <span class="math inline">\(l,r\)</span>相差巨大，所以不能直接暴力建 <spanclass="math inline">\(\mathtt{AC}\)</span> 自动机。</p><p>容易发现，暴力 <span class="math inline">\(\mathtt{AC}\)</span>自动机中有很多节点，以它为根的子树都是一个<strong>满十叉树</strong>，而这些树并不那么有用。</p><p>例如 <span class="math inline">\([1000,2333]\)</span> 间，枚举到<span class="math inline">\(11\_\,\_\)</span>时，后面怎么填都行，而我们朴素dp会把每个都跑一次。</p><p>显然我们会想到把这些节点缩起来。考虑将一个深度为 <spanclass="math inline">\(l\)</span> 的满十叉树缩成一个点（有 <spanclass="math inline">\(10^{l}\)</span> 个叶结点的满十叉树）</p><p>于是，当走到这个点的时候，再任意走 <spanclass="math inline">\(l\)</span> 步（但是至少走 <spanclass="math inline">\(l\)</span>步才能产生贡献），就一定能产生一个匹配</p><p>也就是说我们对这个根节点打上一个长度为 <spanclass="math inline">\(l\)</span> 的标记，表示只要再走 <spanclass="math inline">\(l\)</span> 步就可以得到 <spanclass="math inline">\(1\)</span> 的贡献</p><p>当然，一个点可能被打上多个标记。因此实际上，我们对一个点存储的信息是：长度为<span class="math inline">\(l\)</span> 的标记的数量。</p><p>这样就比刚才的更好更早多了，可以通过 <spanclass="math inline">\(\mathtt{dfs}\)</span>构造，思想类似于数位dp，详见代码。</p><p>对于 dp 的转移，只需要枚举下一个字符是 <spanclass="math inline">\(\mathtt{0 \sim 9}\)</span> 中的哪一个，然后去<span class="math inline">\(\mathtt{AC}\)</span> 自动机上跑，</p><p>再根据当前串长 <span class="math inline">\(l\)</span>决定加入哪些标记。具体地，设串长为 <spanclass="math inline">\(l\)</span> ，则长度小于 <spanclass="math inline">\(l\)</span> 的标记都是有效的，考虑前缀和处理。</p><p>最后就是输出方案的问题，因为要求字典序最小，而传统的转移方向会求出翻转后字典序最小的串。</p><p>因此考虑换一个转移方向。用 <spanclass="math inline">\(f_{i,j}\)</span> 表示总长度为 <spanclass="math inline">\(i\)</span> 的串，<strong>初始时自动机在位置 <spanclass="math inline">\(j\)</span></strong> 所可以获得的最大权值。</p><p>这里的区别在于：一般是默认从 <spanclass="math inline">\(\mathtt{AC}\)</span>自动机的根出发，枚举最后到了哪里。</p><p>设自动机转移 <span class="math inline">\(j \to k\)</span> ，则我们用<span class="math inline">\(f_{i+1,k}\)</span> 去更新 <spanclass="math inline">\(f_{i,j}\)</span>，这样就可以顺便记录选哪个字符更优，从而输出方案</p><p>时间复杂度 <span class="math inline">\(\mathcal{O}(n \log r \cdot\Sigma^2)\)</span> ，其中 <span class="math inline">\(\Sigma=10\)</span>为字符集大小，<span class="math inline">\(r = 10^{800}\)</span>为值域。</p><p>代码：</p><pre

Change G</a></p><blockquote><p><strong>题意</strong>：</p><p>Farmer John 在市场上为他的农场购买物资。 他的口袋里有 <spanclass="math inline">\(k\)</span> 个硬币 <span class="math inline">\((1\le k \le 16)\)</span> ，每个硬币的价值在<spanclass="math inline">\(1\sim 10^8\)</span> 范围内。 FJ 想进行一连串的<span class="math inline">\(n\)</span> 次购买 <spanclass="math inline">\((1 \le n \le 10^5)\)</span> ，其中第 <spanclass="math inline">\(1\)</span> 次购买需要花费 <spanclass="math inline">\(c_i\)</span> 个单位的钱<spanclass="math inline">\((1 \le c_i \le 10^4)\)</span> 。当他进行这一连串的购买时，他可以定期停下来，用一枚硬币来支付自他上次付款以来的所有购买（当然，他使用的这枚硬币必须足够大，以支付所有这些购买）。不幸的是，市场上的小贩完全没有零钱，所以每当 FJ使用大于他所欠的钱的硬币时，他都很遗憾地没有收到任何零钱的回报！请计算出最大的金额。</p><p>请计算 FJ 在依次进行了 <span class="math inline">\(n\)</span>次购买后，最终能得到的最大金额。 如果 FJ 不可能完成他所有的购买，则输出<span class="math inline">\(-1\)</span>。</p><p><strong>输入格式</strong>：</p><p>第 <span class="math inline">\(1\)</span> 行，两个整数，<spanclass="math inline">\(k\)</span> 和 <spanclass="math inline">\(n\)</span> 。</p><p>第 <span class="math inline">\(2\ \sim \ k+1\)</span> 行，每一行包含FJ 的一个硬币的金额。</p><p>第 <span class="math inline">\(2+k\ \sim \ n + k + 1\)</span> 行，这<span class="math inline">\(n\)</span> 行包含 FJ打算购买的东西的费用。</p><p><strong>输出格式</strong>：</p><p>第1行，FJ 最终能得到的最大金额，如果 FJ 不能完成所有的购买，则输出<span class="math inline">\(-1\)</span>。</p></blockquote><p>得到的最大金额一定时，硬币的状态不唯一，因此不能二分。</p><p>于是考虑枚举所有的状态，但是每次都暴力检验复杂度太高了</p><p>注意到很多的状态之间存在联系，比如某个状态不能成功购买，但是后面加上了几个硬币就能买了</p><p>设 <span class="math inline">\(f_i\)</span> 表示状态为 <spanclass="math inline">\(i\)</span>时最多能买到几号物品。不妨记每个硬币的面额为 <spanclass="math inline">\(v_i\)</span> 。</p><p>状态可以转移至 <span class="math inline">\(f_j\)</span> 当且仅当<span class="math inline">\(j = i\, \cup\,\{k\},~k \in (\sim i)\)</span>。记 <span class="math inline">\(r=p\)</span> 为使得 <spanclass="math inline">\(\sum_{t = f_i}^{r} v_t \le w_k\)</span>成立的最大值，则 <span class="math display">\[f_j \uparrow p\]</span> 这个 <span class="math inline">\(p\)</span>可以二分得到，只需要预处理下 <span class="math inline">\(v_i\)</span>的前缀和。并且当某个 <span class="math inline">\(f_i = n\)</span>时，尝试更新一下当前的答案。</p><p>时间复杂度 <span class="math inline">\(\mathcal{O}(2^kk \logn)\)</span></p><p>代码：</p><pre class="line-numbers language-cpp" data-language="cpp"><code

inline">\(M\)</span>条小径，每条小径都是单向的，连接两个小树丛，上面都有一定数量的蘑菇。q779和 cxy经过某条小径一次，可以采走这条路上所有的蘑菇。由于森林是一片神奇的沃土，所以一条路上的蘑菇被采过后，又会长出一些新的蘑菇，数量为原来蘑菇的数量乘上这条路的“恢复系数”<span class="math inline">\(c\)</span> ，再下取整。</p><p>比如，一条路上有 <span class="math inline">\(4\)</span>个蘑菇，这条路的“恢复系数”为 <span class="math inline">\(c =0.7\)</span>，则第一~四次经过这条路径所能采到的蘑菇数量分别为 <spanclass="math inline">\(4,2,1,0\)</span> 。</p><p>现在，q779 和 cxy 从 <span class="math inline">\(S\)</span>号小树丛出发，求他们最多能采到多少蘑菇。</p><p><strong>输入格式</strong>：</p><p>第一行两个整数，<span class="math inline">\(N\)</span> 和 <spanclass="math inline">\(M\)</span>。</p><p>第二行到第 <span class="math inline">\(M+1\)</span>行，每行四个数，分别表示一条小路的起点、终点、初始蘑菇数和恢复系数。</p><p>第 <span class="math inline">\(M+2\)</span> 行，一个整数 <spanclass="math inline">\(S\)</span>。</p><p><strong>输出格式</strong>：</p><p>一行一个整数，表示最多能采到多少蘑菇，保证答案不超过 <spanclass="math inline">\(2^{31}-1\)</span>。</p><p><strong>数据范围</strong>：</p><p><span class="math inline">\(1 \le N\le 8\times 10^4,~1\le M\le2\times 10^5,~0\le c\le 0.8\)</span> 且最多有一位小数， <spanclass="math inline">\(1\le S\le N\)</span>。</p></blockquote><p>复活后的第一篇题解，<del>也是一道热身题</del>。无论如何，愿我圆梦NOIP。</p><p>注意到一条边可以走无数遍，那么任何强连通分量都可以走到不长蘑菇为止。</p><p>考虑缩点并预处理每个强连通分量的答案，然后就变成简单的 DAG 上跑topo+dp 了</p><p>时间复杂度 <span class="math

href="https://www.luogu.com.cn/problem/CF1202E">CF1202EYou Are Given Some Strings...</a></p><blockquote><p><strong>题意</strong>：</p><p>给定文本串 <span class="math inline">\(t\)</span> 和 <spanclass="math inline">\(n\)</span> 个模式串 <spanclass="math inline">\(s_i\)</span> ，求 <span class="math display">\[\sum_{i=1}^n\sum_{j=1}^nf(s_i + s_j)\]</span> <span class="math inline">\(f(s)\)</span> 定义为 <spanclass="math inline">\(s\)</span> 在 <spanclass="math inline">\(t\)</span> 中出现的次数，<spanclass="math inline">\(s_i+s_j\)</span> 定义为拼接字符串 <spanclass="math inline">\(s_i\)</span> 和 <spanclass="math inline">\(s_j\)</span> 。</p><p><strong>输入格式</strong>：</p><p>一行 <span class="math inline">\(t\)</span> ，一行 <spanclass="math inline">\(n\)</span> ，接下来 <spanclass="math inline">\(n\)</span> 行 <spanclass="math inline">\(s_i\)</span> 。</p><p><strong>输出格式</strong>：</p><p>一行，答案。</p><p><strong>数据范围</strong>：</p><p><span class="math inline">\(1\le |t|,\sum |s_i| \le 2\times10^5\)</span> 。</p></blockquote><p>这种题肯定是考虑某个串的贡献啦。</p><p>这里我们考虑枚举划分点 <span class="math inline">\(x\)</span>。记该点前为 <span class="math inline">\(s_i\)</span> ，该点后为 <spanclass="math inline">\(s_j\)</span></p><p>统计出每个 <span class="math inline">\(x\)</span> 的 <spanclass="math inline">\(f(x),g(x+1)\)</span> 分别表示前后的个数。</p><p>怎么统计呢？注意到 <span class="math inline">\(f(x)\)</span> 其实就是<span class="math inline">\(t_{1 \cdots x}\)</span>的后缀中有几个已知子串，<span class="math inline">\(g(x)\)</span>就是反串的 <span class="math inline">\(f(x)\)</span></p><p>这个东西可以用 AC 自动机来搞。就是直接在模式串上建 AC自动机然后跑一遍 <span class="math inline">\(t\)</span> 。</p><p>考虑 fail指针指向的是根到当前串的最长后缀，则所求等价于为模式串的后缀的数量。</p><p>根据 AC 自动机的板子可以知道，这个只要在 fail 树上求个和就好了。</p><p>时间复杂度 <span class="math inline">\(\mathcal{O}(\sum |s_i| \times|\Sigma|)\)</span></p><p>代码：</p><pre class="line-numbers language-cpp" data-language="cpp"><code class="language-cpp"><span class="token macro property"><span class="token

href="https://www.luogu.com.cn/problem/CF1202E">CF1202EYou Are Given Some Strings...</a></p><blockquote><p><strong>题意</strong>：</p><p>给定文本串 <span class="math inline">\(t\)</span> 和 <spanclass="math inline">\(n\)</span> 个模式串 <spanclass="math inline">\(s_i\)</span> ，求 <span class="math display">\[\sum_{i=1}^n\sum_{j=1}^nf(s_i + s_j)\]</span> <span class="math inline">\(f(s)\)</span> 定义为 <spanclass="math inline">\(s\)</span> 在 <spanclass="math inline">\(t\)</span> 中出现的次数，<spanclass="math inline">\(s_i+s_j\)</span> 定义为拼接字符串 <spanclass="math inline">\(s_i\)</span> 和 <spanclass="math inline">\(s_j\)</span> 。</p><p><strong>输入格式</strong>：</p><p>一行 <span class="math inline">\(t\)</span> ，一行 <spanclass="math inline">\(n\)</span> ，接下来 <spanclass="math inline">\(n\)</span> 行 <spanclass="math inline">\(s_i\)</span> 。</p><p><strong>输出格式</strong>：</p><p>一行，答案。</p><p><strong>数据范围</strong>：</p><p><span class="math inline">\(1\le |t|,\sum |s_i| \le 2\times10^5\)</span> 。</p></blockquote><p>这种题肯定是考虑某个串的贡献啦。</p><p>这里我们考虑枚举划分点 <span class="math inline">\(x\)</span>。记该点前为 <span class="math inline">\(s_i\)</span> ，该点后为 <spanclass="math inline">\(s_j\)</span></p><p>统计出每个 <span class="math inline">\(x\)</span> 的 <spanclass="math inline">\(f(x),g(x+1)\)</span> 分别表示前后的个数。</p><p>怎么统计呢？注意到 <span class="math inline">\(f(x)\)</span> 其实就是<span class="math inline">\(t_{1 \cdots x}\)</span>的后缀中有几个已知子串，<span class="math inline">\(g(x)\)</span>就是反串的 <span class="math inline">\(f(x)\)</span></p><p>这个东西可以用 AC 自动机来搞。就是直接在模式串上建 AC自动机然后跑一遍 <span class="math inline">\(t\)</span> 。</p><p>考虑 fail指针指向的是根到当前串的最长后缀，则所求等价于为模式串的后缀的数量。</p><p>根据 AC 自动机的板子可以知道，这个只要在 fail 树上求个和就好了。</p><p>时间复杂度 <span class="math inline">\(\mathcal{O}(\sum |s_i| \times|\Sigma|)\)</span></p><p>代码：</p><pre class="line-numbers language-cpp" data-language="cpp"><code class="language-cpp"><span class="token macro property"><span class="token

和恐怖的奴隶主</a></p><blockquote><p><strong>题意</strong>：</p><p>小 Y 是一个喜欢玩游戏的 OIer。一天，她正在玩一款游戏，要打一个Boss。</p><p>虽然这个 Boss 有 <span class="math inline">\(10^{100}\)</span>点生命值，但它只带了一个随从——一个只有 <spanclass="math inline">\(m\)</span> 点生命值的 “恐怖的奴隶主”。</p><p>这个 “恐怖的奴隶主”有一个特殊的技能：每当它被扣减生命值但没有死亡（死亡即生命值 <spanclass="math inline">\(\leq 0\)</span>），且 Boss 的随从数量小于上限<span class="math inline">\(k\)</span>，便会召唤一个新的具有 <spanclass="math inline">\(m\)</span> 点生命值的 “恐怖的奴隶主”。</p><p>现在小 Y 可以进行 <span class="math inline">\(n\)</span>次攻击，每次攻击时，会从 Boss 以及 Boss的所有随从中的等概率随机选择一个，并扣减 <spanclass="math inline">\(1\)</span> 点生命值，她想知道进行 <spanclass="math inline">\(n\)</span> 次攻击后扣减 Boss的生命值点数的期望。为了避免精度误差，你的答案需要对 <spanclass="math inline">\(998244353\)</span> 取模。</p><p><strong>输入格式</strong>：</p><p>从标准输入读入数据。</p><p>输入第一行包含三个正整数 <span class="math inline">\(T, m,k\)</span>，<span class="math inline">\(T\)</span> 表示询问组数，<spanclass="math inline">\(m, k\)</span> 的含义见题目描述。</p><p>接下来 <span class="math inline">\(T\)</span> 行，每行包含一个正整数<span class="math inline">\(n\)</span>，表示询问进行 <spanclass="math inline">\(n\)</span> 次攻击后扣减 Boss的生命值点数的期望。</p><p><strong>输出格式</strong>：</p><p>输出共 <span class="math inline">\(T\)</span>行，对于每个询问输出一行一个非负整数，表示该询问的答案对 <spanclass="math inline">\(998244353\)</span> 取模的结果。</p><p>可以证明，所求期望一定是一个有理数，设其为 <spanclass="math inline">\(\frac{p}{q}\)</span>（<spanclass="math inline">\(\mathrm{gcd}(p,q) = 1\)</span>），那么你输出的数<span class="math inline">\(x\)</span> 要满足 <spanclass="math inline">\(p \equiv qx \pmod{998244353}\)</span>。</p><p><strong>数据范围</strong>：</p><p><span class="math inline">\(1 \le T \le 1000,~1 \le n \le 10^{18},~m= 1,2,3,~1\le k \le 8\)</span></p></blockquote><p><del>据说概率要顺推，期望要逆推？</del></p><p>容易想到是矩阵快速幂优化期望dp。</p><p>注意到 <span class="math inline">\(m\)</span> 很小，且 <spanclass="math inline">\(k\)</span>也很小，所以我们直接枚举每个血量各有多少人。</p><p>设 <span class="math inline">\(f_{i,a,b,c}\)</span> 表示前 <spanclass="math inline">\(i\)</span> 次攻击后，场上有 <spanclass="math inline">\(a\)</span> 个 <spanclass="math inline">\(1\)</span> 点血，<spanclass="math inline">\(b\)</span> 个 <spanclass="math inline">\(2\)</span> 点血，<spanclass="math inline">\(c\)</span> 个 <spanclass="math inline">\(3\)</span> 点血的期望。</p><p>转移很简单，就是乘一乘概率系数啥的，这里就略去了。<del>或者可以看参考文献[2]的分析</del></p><p>注意到 <span class="math inline">\(f_i\)</span> 只有 <spanclass="math inline">\(165 + 1\)</span>个状态，其中一个是额外加上的，表示 boss 扣血的期望 <spanclass="math inline">\(g\)</span> 。</p><p><br></p><p>关于构建矩阵，估计也有很多人和我一样知道矩阵快速幂，但不会代码实现矩阵的构建。</p><p>最开始学斐波那契数列的矩阵快速幂方法时，只是看这个矩阵挺好用，怎么正好就推出来下一个。</p><p>现在做了这道题，感觉对这个矩阵的理解又加深了一些。</p><p>对于转移矩阵 <span class="math inline">\(M\)</span> ，考察 <spanclass="math inline">\(M_{i,j}\)</span> 的数学意义。</p><p>状态数组（行向量）左乘 <span class="math inline">\(M_{i,j}\)</span>其实就是：<strong>新向量第 <span class="math inline">\(i\)</span>个状态由原向量第 <span class="math inline">\(j\)</span>个状态转移过来时的系数</strong>。</p><p>举个例子，斐波那契数列 <span class="math display">\[\begin{bmatrix}f_i&amp;f_{i-1}\end{bmatrix}\times\begin{bmatrix}1&amp;1\\1&amp;0\end{bmatrix}=\begin{bmatrix}f_{i+1}&amp;f_{i}\end{bmatrix}\]</span> 因为有递推式 <span class="math inline">\(f_1=1,~f_2=1,~f_i =f_{i-1} + f_{i-2}\)</span>。<del>观察一下，相信你就懂了，反正我一看就懂了。</del></p><p><br></p><p>然而直接矩阵快速幂是 <spanclass="math inline">\(\mathcal{O}(T166^3\log n)\)</span> 的，会TLE。</p><p>考虑预处理 <span class="math inline">\(2^k\)</span>次幂的矩阵，这样查询就可以少掉一个 <span class="math inline">\(M\timesM\)</span> 的第 <span class="math inline">\(k\)</span> 维枚举了。</p><p>时间复杂度 <span class="math inline">\(\mathcal{O}(T166^2\logn)\)</span></p><p>代码：（这题卡常，可以用 <code>__int128</code> 优化取模操作）</p><pre class="line-numbers language-cpp" data-language="cpp"><code class="language-cpp"><span class="token

和恐怖的奴隶主</a></p><blockquote><p><strong>题意</strong>：</p><p>小 Y 是一个喜欢玩游戏的 OIer。一天，她正在玩一款游戏，要打一个Boss。</p><p>虽然这个 Boss 有 <span class="math inline">\(10^{100}\)</span>点生命值，但它只带了一个随从——一个只有 <spanclass="math inline">\(m\)</span> 点生命值的 “恐怖的奴隶主”。</p><p>这个 “恐怖的奴隶主”有一个特殊的技能：每当它被扣减生命值但没有死亡（死亡即生命值 <spanclass="math inline">\(\leq 0\)</span>），且 Boss 的随从数量小于上限<span class="math inline">\(k\)</span>，便会召唤一个新的具有 <spanclass="math inline">\(m\)</span> 点生命值的 “恐怖的奴隶主”。</p><p>现在小 Y 可以进行 <span class="math inline">\(n\)</span>次攻击，每次攻击时，会从 Boss 以及 Boss的所有随从中的等概率随机选择一个，并扣减 <spanclass="math inline">\(1\)</span> 点生命值，她想知道进行 <spanclass="math inline">\(n\)</span> 次攻击后扣减 Boss的生命值点数的期望。为了避免精度误差，你的答案需要对 <spanclass="math inline">\(998244353\)</span> 取模。</p><p><strong>输入格式</strong>：</p><p>从标准输入读入数据。</p><p>输入第一行包含三个正整数 <span class="math inline">\(T, m,k\)</span>，<span class="math inline">\(T\)</span> 表示询问组数，<spanclass="math inline">\(m, k\)</span> 的含义见题目描述。</p><p>接下来 <span class="math inline">\(T\)</span> 行，每行包含一个正整数<span class="math inline">\(n\)</span>，表示询问进行 <spanclass="math inline">\(n\)</span> 次攻击后扣减 Boss的生命值点数的期望。</p><p><strong>输出格式</strong>：</p><p>输出共 <span class="math inline">\(T\)</span>行，对于每个询问输出一行一个非负整数，表示该询问的答案对 <spanclass="math inline">\(998244353\)</span> 取模的结果。</p><p>可以证明，所求期望一定是一个有理数，设其为 <spanclass="math inline">\(\frac{p}{q}\)</span>（<spanclass="math inline">\(\mathrm{gcd}(p,q) = 1\)</span>），那么你输出的数<span class="math inline">\(x\)</span> 要满足 <spanclass="math inline">\(p \equiv qx \pmod{998244353}\)</span>。</p><p><strong>数据范围</strong>：</p><p><span class="math inline">\(1 \le T \le 1000,~1 \le n \le 10^{18},~m= 1,2,3,~1\le k \le 8\)</span></p></blockquote><p><del>据说概率要顺推，期望要逆推？</del></p><p>容易想到是矩阵快速幂优化期望dp。</p><p>注意到 <span class="math inline">\(m\)</span> 很小，且 <spanclass="math inline">\(k\)</span>也很小，所以我们直接枚举每个血量各有多少人。</p><p>设 <span class="math inline">\(f_{i,a,b,c}\)</span> 表示前 <spanclass="math inline">\(i\)</span> 次攻击后，场上有 <spanclass="math inline">\(a\)</span> 个 <spanclass="math inline">\(1\)</span> 点血，<spanclass="math inline">\(b\)</span> 个 <spanclass="math inline">\(2\)</span> 点血，<spanclass="math inline">\(c\)</span> 个 <spanclass="math inline">\(3\)</span> 点血的期望。</p><p>转移很简单，就是乘一乘概率系数啥的，这里就略去了。<del>或者可以看参考文献[2]的分析</del></p><p>注意到 <span class="math inline">\(f_i\)</span> 只有 <spanclass="math inline">\(165 + 1\)</span>个状态，其中一个是额外加上的，表示 boss 扣血的期望 <spanclass="math inline">\(g\)</span> 。</p><p><br></p><p>关于构建矩阵，估计也有很多人和我一样知道矩阵快速幂，但不会代码实现矩阵的构建。</p><p>最开始学斐波那契数列的矩阵快速幂方法时，只是看这个矩阵挺好用，怎么正好就推出来下一个。</p><p>现在做了这道题，感觉对这个矩阵的理解又加深了一些。</p><p>对于转移矩阵 <span class="math inline">\(M\)</span> ，考察 <spanclass="math inline">\(M_{i,j}\)</span> 的数学意义。</p><p>状态数组（行向量）左乘 <span class="math inline">\(M_{i,j}\)</span>其实就是：<strong>「原向量第 <span class="math inline">\(i\)</span>个状态」转移到「新向量第 <span class="math inline">\(j\)</span>个状态」时乘的系数</strong>。</p><p>也可以说，「新向量第 <span class="math inline">\(j\)</span>个状态」由「原向量第 <span class="math inline">\(i\)</span>个状态」转移过来时乘的系数。</p><p>举个例子，斐波那契数列 <span class="math display">\[\begin{bmatrix}f_i&amp;f_{i-1}\end{bmatrix}\times\begin{bmatrix}1&amp;1\\1&amp;0\end{bmatrix}=\begin{bmatrix}f_{i+1}&amp;f_{i}\end{bmatrix}\]</span> 因为有递推式 <span class="math inline">\(f_1=1,~f_2=1,~f_i =f_{i-1} + f_{i-2}\)</span> 。</p><p>本质上矩阵就是多个行向量构成的，因此对于矩阵乘法，我们也可以用这样的方式理解，如<span class="math display">\[\begin{bmatrix}1&amp;2\\3&amp;4\end{bmatrix} \times\begin{bmatrix}5&amp;6\\7&amp;8\end{bmatrix}= \begin{bmatrix}5 \times 1 + 7 \times 2 &amp; 6 \times 1+ 8 \times 2 \\5 \times 3 + 7 \times 4&amp;6 \times 3 + 8 \times 4\end{bmatrix}= \begin{bmatrix}19&amp;22\\43&amp;50\end{bmatrix}\]</span> 属于是复习一下矩阵快速幂了（</p><p><br></p><p>然而直接矩阵快速幂是 <spanclass="math inline">\(\mathcal{O}(T166^3\log n)\)</span> 的，会TLE。</p><p>考虑预处理 <span class="math inline">\(2^k\)</span>次幂的矩阵，这样查询就可以少掉一个 <span class="math inline">\(M\timesM\)</span> 的第 <span class="math inline">\(k\)</span> 维枚举了。</p><p>时间复杂度 <span class="math inline">\(\mathcal{O}(T166^2\logn)\)</span></p><p>代码：（这题卡常，可以用 <code>__int128</code> 优化取模操作）</p><pre class="line-numbers language-cpp" data-language="cpp"><code class="language-cpp"><span class="token

向上左或向上右走。它可以选择从最低行哪个节点开始他的旅程。每个格子上有0-9颗豌豆，而士兵想移动到最上一行并且积累到尽可能多的豌豆。同时，因为这个士兵必须把豌豆平均分给自己和他的k个兄弟，他所收集到的豌豆必须是k+1的倍数。请找到他可以收集到的最多豌豆，并确定他的操作序列。</p><p>规定士兵不能手动扔出豌豆，并且他必须捡起所到达的每一个格子的所有豌豆。</p><p>输入格式： 第一行三个整数 <span class="math inline">\(n,m,k(2 \le n,m\le 100, 0 \le k \le 10)\)</span> 行数、列数、士兵的兄弟们。 接下来一个<span class="math inline">\(n \times

字符串的子字符串是该字符串的连续子序列。例如，BCD是ABCDEF的子串。你得到了两个字符串s1,s2和另一个名为virus的字符串。你的任务是找到s1和s2的最长公共子序列，同时不包含virus子字符串。</p></blockquote><p>升级版的最长公共子序列问题（LCS问题）</p><p>考虑增加一维，称为与 <span class="math

m的桌子，桌子的每一个单元格上都有一个字符，字符集为("D","I","M","A")。</p><p>Inna实在是太爱Dima了，所以她想在桌子上找出一条最长的路线，使得这条路线中包含尽可能多的Dima的名字（有序，即必须是连续的DIMA）。</p><p>Inna的路线选取方式会遵循以下原则：</p><p>1.一开始，Inna会在桌子上找到所有的"D"，把他们作为起点。</p><p>2.Inna会在当前格子的周围四个相邻的格子中选取一个格子，她会从"D"走到"I"，从"I"走到"M"，从"M"走到"A"。这样，她就认为自己走完了一次Dima的名字。</p><p>3.Inna每走完一个格子，就会在该格子四周相邻的四个格子中选一个走，即上下左右四个方向，（当然，她不能走出这张桌子）。Inna从不跳过一个字母。因此，从字母"D"开始，她总是走到字母"I"，从字母"I"开始，她总是走到字母"M"，从字母"M"开始，她总是走到字母"A"，从字母"A"开始，她总是走到字母"D"。</p><p>因为桌子的不同，Inna能走的Dima的名字的次数也不同，有时她可以走有限次，有时她可以走无限次，有时她甚至不能走完一次Dima的名字。</p><p>现在，她想知道她能否至少走完一次Dima的名字。若可以，她最多能走多少次或者她能否走无限次？</p></blockquote><p>纯记忆化搜索</p><p>从每个<code>D</code>都跑一下</p><p>对于无限的情况，</p><p>只要判断下一个可行格子是不是已经visited了</p><p>注意记忆化搜索使用dis数组更新答案</p><p>不是靠每次dfs的step</p><p>代码：</p><pre

m的桌子，桌子的每一个单元格上都有一个字符，字符集为("D","I","M","A")。</p><p>Inna实在是太爱Dima了，所以她想在桌子上找出一条最长的路线，使得这条路线中包含尽可能多的Dima的名字（有序，即必须是连续的DIMA）。</p><p>Inna的路线选取方式会遵循以下原则：</p><p>1.一开始，Inna会在桌子上找到所有的"D"，把他们作为起点。</p><p>2.Inna会在当前格子的周围四个相邻的格子中选取一个格子，她会从"D"走到"I"，从"I"走到"M"，从"M"走到"A"。这样，她就认为自己走完了一次Dima的名字。</p><p>3.Inna每走完一个格子，就会在该格子四周相邻的四个格子中选一个走，即上下左右四个方向，（当然，她不能走出这张桌子）。Inna从不跳过一个字母。因此，从字母"D"开始，她总是走到字母"I"，从字母"I"开始，她总是走到字母"M"，从字母"M"开始，她总是走到字母"A"，从字母"A"开始，她总是走到字母"D"。</p><p>因为桌子的不同，Inna能走的Dima的名字的次数也不同，有时她可以走有限次，有时她可以走无限次，有时她甚至不能走完一次Dima的名字。</p><p>现在，她想知道她能否至少走完一次Dima的名字。若可以，她最多能走多少次或者她能否走无限次？</p></blockquote><p>纯记忆化搜索</p><p>从每个<code>D</code>都跑一下</p><p>对于无限的情况，</p><p>只要判断下一个可行格子是不是已经visited了</p><p>注意记忆化搜索使用dis数组更新答案</p><p>不是靠每次dfs的step</p><p>代码：</p><pre

尽可能接近。</p></blockquote><p>把所有连通块的大小求出来，统计每个大小各有几个连通块</p><p>然后二进制优化的多重背包，不过这道题是可行性问题</p><p>代码：</p><pre class="line-numbers language-cpp" data-language="cpp"><code class="language-cpp"><span

N\)</span>的方阵，为了保证队伍在行进中整齐划一，C君会跟在仪仗队的左后方，根据其视线所及的学生人数来判断队伍是否整齐（如下图）。</p><p><imgsrc="https://img-blog.csdnimg.cn/img_convert/c8ec2164ba56f7e14ecc1a4af2b7f6ef.png" /></p><p>现在，C 君希望你告诉他队伍整齐时能看到的学生人数。</p></blockquote><p>稍微画一画图，可以发现我们只要求对角线以下的个数，然后把答案乘 <spanclass="math inline">\(2\)</span> 加 <spanclass="math inline">\(1\)</span> 即可</p><p><img

<spanclass="math inline">\(n\)</span> 名学生中选 <spanclass="math inline">\(m\)</span> 人当学霸，但有 <spanclass="math inline">\(k\)</span>人实力相当，如果实力相当的人中，一部分被选上，另一部分没有，同学们就会抗议。所以老师想请你帮他求出他该选多少学霸，才能既不让同学们抗议，又与原来的<span class="math inline">\(m\)</span> 尽可能接近。</p></blockquote><p>把所有连通块的大小求出来，统计每个大小各有几个连通块</p><p>然后二进制优化的多重背包，不过这道题是可行性问题</p><p>代码：</p><pre class="line-numbers language-cpp" data-language="cpp"><code class="language-cpp"><span

的新背包问题</a></p><blockquote><p><strong>题意</strong>：</p><p>失忆的 Eden总想努力地回忆起过去，然而总是只能清晰地记得那种思念的感觉，却不能回忆起她的音容笑貌。</p><p>记忆中，她总是喜欢给 Eden 出谜题：在 valentine's day的夜晚，两人在闹市中闲逛时，望着礼品店里精巧玲珑的各式玩偶，她突发奇想，问了Eden 这样的一个问题：有 <span class="math inline">\(n\)</span>个玩偶，每个玩偶有对应的价值、价钱，每个玩偶都可以被买有限次，在携带的价钱<span class="math inline">\(m\)</span>固定的情况下，如何选择买哪些玩偶以及每个玩偶买多少个，才能使得选择的玩偶总价钱不超过<span class="math inline">\(m\)</span>，且价值和最大。</p><p>众所周知的，这是一个很经典的多重背包问题，Eden很快解决了，不过她似乎因为自己的问题被飞快解决感到了一丝不高兴，于是她希望把问题加难：多次询问，每次询问都将给出新的总价钱，并且会去掉某个玩偶（即这个玩偶不能被选择），再问此时的多重背包的答案（即前一段所叙述的问题）。</p><p>这下 Eden 犯难了，不过 Eden 不希望自己被难住，你能帮帮他么？</p><p>数据范围：</p><ul><li>对于 <span class="math inline">\(100\%\)</span> 的数据，保证 <spanclass="math inline">\(1 \leq n \leq 1000\)</span>，<spanclass="math inline">\(1 \leq q \leq 3\times 10^5\)</span>， <spanclass="math inline">\(1 \leq a_i,b_i,c_i \leq 100\)</span>，<spanclass="math inline">\(0 \leq d_i &lt; n\)</span>，<spanclass="math inline">\(0 \leq e_i \leq 1000\)</span>。</li><li><span class="math inline">\(\sum e_i \le 2\times 10^7\)</span>（讨论区补充的）</li></ul></blockquote><p>不难发现，如果不考虑第 <span class="math inline">\(p\)</span>个物品</p><p>最大的价值其实就是 <span class="math inline">\(1\sim p-1\)</span> 和<span class="math inline">\(p+1 \sim n\)</span> 的最大价值</p><p>考虑正反分别跑一遍多重背包，然后对于每个询问暴力合并泛化物品</p><p>单调队列优化更快一点，当然二进制拆分也是可以过的。</p><p>二进制拆分写法，时间复杂度 <span

的新背包问题</a></p><blockquote><p><strong>题意</strong>：</p><p>失忆的 Eden总想努力地回忆起过去，然而总是只能清晰地记得那种思念的感觉，却不能回忆起她的音容笑貌。</p><p>记忆中，她总是喜欢给 Eden 出谜题：在 valentine's day的夜晚，两人在闹市中闲逛时，望着礼品店里精巧玲珑的各式玩偶，她突发奇想，问了Eden 这样的一个问题：有 <span class="math inline">\(n\)</span>个玩偶，每个玩偶有对应的价值、价钱，每个玩偶都可以被买有限次，在携带的价钱<span class="math inline">\(m\)</span>固定的情况下，如何选择买哪些玩偶以及每个玩偶买多少个，才能使得选择的玩偶总价钱不超过<span class="math inline">\(m\)</span>，且价值和最大。</p><p>众所周知的，这是一个很经典的多重背包问题，Eden很快解决了，不过她似乎因为自己的问题被飞快解决感到了一丝不高兴，于是她希望把问题加难：多次询问，每次询问都将给出新的总价钱，并且会去掉某个玩偶（即这个玩偶不能被选择），再问此时的多重背包的答案（即前一段所叙述的问题）。</p><p>这下 Eden 犯难了，不过 Eden 不希望自己被难住，你能帮帮他么？</p><p>数据范围：</p><ul><li>对于 <span class="math inline">\(100\%\)</span> 的数据，保证 <spanclass="math inline">\(1 \leq n \leq 1000\)</span>，<spanclass="math inline">\(1 \leq q \leq 3\times 10^5\)</span>， <spanclass="math inline">\(1 \leq a_i,b_i,c_i \leq 100\)</span>，<spanclass="math inline">\(0 \leq d_i &lt; n\)</span>，<spanclass="math inline">\(0 \leq e_i \leq 1000\)</span>。</li><li><span class="math inline">\(\sum e_i \le 2\times 10^7\)</span>（讨论区补充的）</li></ul></blockquote><p>不难发现，如果不考虑第 <span class="math inline">\(p\)</span>个物品</p><p>最大的价值其实就是 <span class="math inline">\(1\sim p-1\)</span> 和<span class="math inline">\(p+1 \sim n\)</span> 的最大价值</p><p>考虑正反分别跑一遍多重背包，然后对于每个询问暴力合并泛化物品</p><p>单调队列优化更快一点，当然二进制拆分也是可以过的。</p><p>二进制拆分写法，时间复杂度 <span class="math inline">\(O(m\sum_{i=1}^{n}\log c_i + \sum e_i)\)</span></p><p>代码：</p><pre class="line-numbers language-cpp" data-language="cpp"><code class="language-cpp"><span class="token macro

class="math inline">\(a_n\bmod p\)</span>在<span class="math inline">\(n\)</span> 足够大时为常数</p><p>多组数据 <span class="math inline">\(1\le Q\le 10^3\)</span> ，<spanclass="math inline">\(1 \le p\le

\varphi(m)+\varphi(m)},&amp;b\ge \varphi(m)\end{cases} \pmod{m}\end{aligned}\]</span> 显然当 <span class="math inline">\(n\)</span> 足够大时，有<span class="math inline">\(a_{n-1} &gt; \varphi(p)\)</span></p><p>则 <span class="math display">\[a_{n}\bmod p = 2^{a_{n-1}\bmod\, \varphi(p)+\varphi(p)}\bmod p\]</span> 可以发现原问题转化为了求解 <span class="math display">\[a_{n-1} \bmod \varphi(p) + \varphi(p)\]</span> 递归处理即可</p><p>关于这个递归为什么是 <span class="math inline">\(O(\logp)\)</span></p><p>显然每一次递归 <span class="math inline">\(p\)</span> 都会变成 <spanclass="math

摩基亚</a></p><blockquote><p><strong>题意</strong>：摩尔瓦多的移动电话公司摩基亚（Mokia）设计出了一种新的用户定位系统。和其他的定位系统一样，它能够迅速回答任何形如“用户C的位置在哪？”的问题，精确到毫米。但其真正高科技之处在于，它能够回答形如“给定区域内有多少名用户？”的问题。</p><p>在定位系统中，世界被认为是一个 <spanclass="math inline">\(w×w\)</span> 的正方形区域，由 <spanclass="math inline">\(1\times 1\)</span>的方格组成。每个方格都有一个坐标 <spanclass="math inline">\((x,y)\)</span>，<span class="math inline">\(1\leqx,y\leq w\)</span>。坐标的编号从 <span class="math inline">\(1\)</span>开始。对于一个 <span class="math inline">\(4\times 4\)</span>的正方形，就有 <span class="math inline">\(1\leq x\leq 4\)</span>，<spanclass="math

<spanclass="math inline">\(x\)</span> ，第三维是 <spanclass="math inline">\(y\)</span> ）</p><p>这里我们甚至不用按时间排序，它本来就是顺序的</p><p>注意到 <span class="math inline">\(w\le 2\times
