Sorting Visualizer

5 algorithms • Real-time
Array Size 50
Speed (steps/sec) 30
Blue = comparing • Orange = swapping • Green = sorted
Tip: Larger arrays highlight the difference between O(n²) and O(n log n) algorithms.

Pathfinding Visualizer

4 algorithms • Editable grid
Click grid to toggle walls. Use mode buttons to set start/end.
