Contribution guide

1. Create an issue where you document your contribution (i.e. mention the algorithm you want to develop the source code for, and the programming language).
2. Propose your changes in a new branch with the name <issue_id> <algorithm_name> <programming_language> and create a pull request.
3. [IMPORTANT] Please make sure to be consistent in terms of project/directories structure and style guide!
4. Wait for review & approvals, and be proud of yourself :) Your contribution is highly appreciated!
