- [Grokking the Coding Interview: Patterns for Coding Questions](https://www.educative.io/courses/grokking-the-coding-interview?aff=x23W) - This course essentially expands upon the questions on this page but approaches the practicing from a questions pattern perspective rather than data structures, which is an approach I also agree with for learning and have personally used to get better at algorithmic problems. The course allows you to practice in Java, Python, C++, JavaScript and also provides sample solutions in those languages. **Learn and understand patterns, not memorize answers!**
