This repo contains a collection of various helpful resources including code, links to sites, tutorials, problemsets etc.
If you want to add something to the repo, just open an issue or hit a PR.
I will be updating it as I find more stuff to add in...stay tuned!
- Codeforces: Most Popular and my favourite.
- Codechef: Nice one, except for long challenges.
- Hackerrank: Best for beginners and clean.
- Hackerearth: Hiring Challenges!
- Atcoder: Great Problems and Contests.
- Topcoder: For more than just Competitive Programming.
- Leetcode: Best for Interview prep. Period.
- Codesignal: If you are done with all of the above ;)

This section contains an organised set of resources, divided into topics, and categorised by the level of complexity(actual, not computational! Lol.)
Topics for people getting started with Competitive Programming.
Topics for people with some experience with CP, but a desire to go above and beyond.
Topics related to highly important concepts and algorithms that are used for solving the most difficult of problems.
