Code Problems

This is my repo full of code problems that I have completed prior to or during an interview, as well as general problem snippets. I hope that all these problems (and solutions) are useful to others for practice and review. Feel free to contribute any solutions and optimisations, and add your own problems that you find as well, as I would love to see them.
