README - How to Contribute

[hemanth-kotagiri]

Hey, @ShreyaDayma-cse. I appreciate your efforts, but there's a lot that needs to be said of your PR.
General Suggestions:

1. Always review Contrubition Guidelines of any repository before you raise a PR.
2. You have not raised an Issue regarding your implementation - and it's essential for the issue to be created before you raising a PR and it also needs to be assigned to you.

Code Review:

1. Please have proper naming conventions with regard to file names.
2. Since you are implementing recursive and iterative approaches, you can either maintain two different PRs or add the implementations as two different methods in the same class with the proper method names.
