OI-Utility is a powerful library for OI contests. It's different from other data structure library. It's fast, safy and easy-to-use. And it's simple enough to extend.
- Cross-platform : There are no external libraries that
OI-Utilityneeds. It may not even need theC++ Standard Library. - Simpler than others : You will understand the its purpose as soon as you see a function. Its naming style is similar to
STL. - More secure : Never use the dynamic memory allocation in order to have less problems and mistakes.
There are two kinds of utilities in this library: Algorithm & Data Structure. All of them have no dependence on each other. By this way, you can just move the source codes to your project. It's easy to find the algorithm you need.
Maybe you wanna use OI-Utility as a external library instead of copying the source code and then compile it. In reality, it is feasible for OI-utility to be used without compiling. You hust need to include it like this:
#include "\OI-Utility\Algorithm\QuickIO.hpp"
using namespace QuickIO;
