This channel is to help programmers who want to perform well in competitive programming contests and technical interviews for big/top companies.

I try to post a variety of problems on Dynamic Programming (DP), Maths, Graph Theory, Trees, String, Sliding Window, Trie, Greedy, 2-D Arrays, 3-D Arrays, Multi-set, Multi-Dimensional Arrays, etc. problems on a regular basis.
