Add commit with the most optimal solution incase of multiple solutions

[vedangwartikar]

Is your feature request related to a problem? Please describe.
Most optimal solution can be added. For ex: My first submission is 68ms (5% faster) but my second submission is 31ms (83% faster). It would be better to add another commit with the better submission data and code.

Describe the solution you'd like
Compare the submission's parameters like runtime, faster than, and memory usage to find out the most optimal submission and add a commit (if needed) accordingly.
