Algorithm Visualizers

Master competitive programming algorithms with interactive step-by-step visualizations. Learn sorting, searching, dynamic programming, graphs, and more with real-time animations.

Interactive Algorithm Visualizer

Algorithm Visualizer

Interactive step-by-step visualization of classical algorithms

Specialized Visualizers

Learn complex algorithms visually, then jump straight into a curated practice set for that topic.

Sorting Algorithms

Interactive visualization of bubble sort, selection sort, quick sort, and more. Watch how different algorithms work step by step.

Graph Algorithms

Shortest paths, BFS/DFS, MST, and more. Build intuition with interactive traces.

Dynamic Programming

State design, transitions, and optimization tricks (knapsack, LIS, digit DP).

Greedy

Exchange argument, sorting by key, and classic counterexamples.

Binary Search

Predicate design, monotonicity, lower_bound/upper_bound patterns.

Trees

Tree traversals, LCA, subtree tricks, rerooting.
