What it does
Hello Algo introduces data structures and algorithms with animated illustrations and executable code examples.
Use an animation to follow a small input, then run the corresponding code and change that input. The two views support checking the same idea in different forms. Language implementations provide options for practising the algorithm in a toolchain you already know. The project is free and beginner-oriented, with one-click runnable code. Its repository applies CC BY-NC-SA 4.0 to text, code and media.
