If the algorithm is working fine, then no need to modify it. Someone from the team has already approved and merged by reviewing it.
Moreover, don't create test cases for other's files. Try to create PR with a new Algorithm problem.

Hi @pomkarnath98! I did not change the original implementation. I only removed the test / driver code from the implementation file and replaced it with a proper (more in-depth) test case.

Why would you dis-encourage people to contribute to already-existing implementations? :( The contribution doc explicitly encourages that.

@pomkarnath98 The repositories of TheAlgorithms are for educational purposes. Here are the reasons why tests are useful even for perfectly coded algorithms:

1. Tests show the learner how to use a particular algorithm.
2. It shows where the algorithm can and should fail.
3. It makes it easier for the maintainers to make sure changes to an algorithm do not break it.

@defaude Please format your code with standard.js.

@defaude I'm really thankful that people like you are getting time to contribute to open sources.
Please, don't take my words in the wrong way. But if you can find any improvement anywhere, you could've raised an issue and then resolved the issue by making this PR.
Your description itself was Refactored.. so that I got confused there.
Anyway, format your code. We'll review and merge :)

Your points are welcome @raklaptudirm.
