Suggesting changes in CONTRIBUTING.md

[3141roy]

For uploading Algorithms and Problems in general, the contributing.md file states :

"In your PR description, be sure to include screenshots that prove that your code works. You are also encouraged to give a small description of your code / doc."

However, I would recommend a minor addition of requiring everyone to mention the problem number in the file name when uploading solutions to Leetcode problems. In this way, it will be easier for contributors to identify if a problem is already submitted by another user or not.

Although most users are following this convention, adding them to the rules will help get rid of benefit of doubt.

Plus it will also reduce the effort of maintainers to verify if a problem was already updated by someone else, thus, increasing the effectiveness of the process.

If you find the suggestion beneficial, please do assign it, so I may change the contributing.md file in the required fashion.

That's a great suggestion. Thanks!
