Remove all duplicate code from the repository

[Pradyuman7]

• Find duplicate codes in the repository (the code does not need be the same, but must do the same thing)
• Move them to a single directory or remove low quality code (make your best judgement)
• Clean up the project with respect to these duplicate codes

This issue must be done by a single contributor, and should contribute to removing all the duplication issues in the repository. Please comment if you'd want to take up this issue, and I'll assign it to you. I will be assigning the issue based on the order of the comment.

Go ahead @aryanlath, please make sure to remove all the duplicate code that you can find from the repository. e.g.
If there are 2 implementation of binary search:
just keep one and keep the one in the directory that makes more sense (like here it would be algrorithms)
