Cpcpp

Warning

I don't excel in CP, so some of the solutions might not be an AC one.

✨ Overview

Here I store some CP solutions I've written in C++ on multiple platforms.

CP, standing for competitive programming, is a kind of sport. CP questions look pretty similar to programming interview questions.
