Add Algorithms

[rudrajit1729]

Add algorithms ranging from most basic to advanced.

Be it graphs, dynamic programming, greedy, or adhoc. Simple to complex, as long it is a valid algorithm put this in bucket.

If domain not present already create a folder under the bucket. (Eg: Dynamic Programming is a domain(if not already there make a folder of the name and push all your codes related to DP there))

You can add Codechef/Hackerrank/Codeforces contest problems provided the contest is already over.
