Step-by-step playback
Pause, move forward, go back, and reset the process whenever you want to inspect a key state.
Interactive algorithm visualization
AlgoDemo
Turn every algorithm step into something you can see.
AlgoDemo helps you explore sorting, trees, hash tables, dynamic programming, stacks, mazes, and more through animated visualizations, synced code highlights, and step-by-step playback controls.
Understand the idea, the state, and the code together.
Pick an algorithm topic and follow how the data changes, which operation is active, and which code line is running. It is built for learning, reviewing, and explaining algorithm behavior clearly.
Clear state highlights
Follow current comparisons, visits, stack changes, paths, and table updates with focused visual cues.
Synced code view
Connect the visual explanation to the implementation as highlighted code lines advance with the demo.
