Many times this happens in competitive programming competitions where 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!

Now you can save your precious time during Competitive Programming Competition.

This is my template which I use in Competitive coding
