A collection of code snippets for competitive programmers, written in C++ for atom editor.

Many times this happens in competitive programming competitions that you've figured out an algorithm for the solution of the problem, which happens to be a standard algorithm. How helpful would it be to have snippets for commonly used concepts/algorithms in competitive programming in that situation, to provide you an edge over fellow competitors as using snippets will improve your accuracy, speed and hence rank!

This repository provides extension for atom-text editor which enables atom users to use c++ coding snippets of algorithms while doing competitive programming.

- For installation, type Ctrl + Shift + P.
- Select Settings View:Install Packages And Themes
- Then search for cpp-competitive-programming-snippets in Packages tab.
- Restart atom.
