I have been trying to cover a lot of commonly used Algorithms/Data Structures and maintain neatly written codes at my repository (since most codes are not neatly written in Competitive Programming in general, and I prefer neatly written codes):

Most of the codes are taken from various sources and already existing Coding Libraries, and many Algorithms/Data Structures are missing which I plan to add soon.

Hope you enjoy and feel free to point out any bugs you notice :)
