Clean example implementations of data structures and algorithms written in different languages.

Contribution

• Contributions are always welcome. Language doesn't matter. Just make sure you're implementing an algorithm.

• There is a list of algorithms, data structures, puzzles and ciphers in IMPLEMENTATIONS.md to give an idea.

• PRs are welcome. To begin developing, follow the structure:

  algorithm_name/language-name/file_name.extension e.g bubble_sort/python/bubble_sort.py

• If there is an implementation of the same algorithm in your language, add your username in front of the file name.

• Please include a description for the algorithm that you are implementing. It doesn't matter if it's copied from somewhere as long as it helps people that are learning new algorithm.

• Graphical examples would be very helpful too.

• Don't forget to include tests.

• Don't remove previous implementations of algorithms. Just add a new file with your own implementation.

• Beautify and cleanup your code for easier reading.
