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. If you have a problem or solution that's not currently not included, please open an issue or pull request! If you're including new content, please make sure you have permission to publish the content you are adding. Under no circumstance should you copy problems online without a visible license or attributions, or from coding interview websites such as Codility.
