Introduction

Mathball is a JavaScript library for competitive programming, implementing optimized algorithms for faster execution.

JavaScript was never built while keeping competitive coding in mind; let us all agree on that. Back in 1995, Brendan Eich developed JavaScript only for adding interactivity to web pages like handling a mouse click. Today, we can build servers, games, mobile apps, IoT apps and even machine learning in the browser is possible with JavaScript.

"Any application that can be written in JavaScript, will eventually be written in JavaScript." -- Atwood's Law.

Hence, I believe maybe its time for people who are well versed with this particular language to finally consider using it in the realm of competitive programming as well.

Installation

You can download the package in your working directory by simply typing in the terminal (for Mac/Linux users) or command prompt (for Windows users):

$ npm install mathball --save

Features

• Numbers' Problem - Complex Number, Find nth Number, Number Checker, Range of Number

• Helper Functions - Performance - Pipe

• Core Tools - Absolute - Add - Average - Binomial Coeff - Convert - Count - Divide - Euler's Totient - Modular Exponent - GCD - LCM - Length - Maximum - Median - Minimum - Modular Inverse - Multiply - Permute - Set Bits - Sort - Subtract - Sum

Examples

You can access all the functions via mathball object, M (or whatever you end up calling it) like so:

let M = require('mathball');

console.log(M.check('palindrome')(1551)); /* true */
console.log(M.check('even')(7)); /* false */
console.log(M.sum([4, 5, 9])); /* 18 */
