Learn Algorithms by Watching Them Run: 65+ Free Visualizers

Most people don't fail algorithms courses because the ideas are too hard — they fail because the ideas stay invisible. A quicksort partition or a DP table fill happens in your head or not at all. The Algorithm Academy makes it happen on screen instead: every algorithm in a standard DSA syllabus, animated one operation at a time, with the pseudocode line that caused each step highlighted as it executes.

What's covered

• Searching: linear, binary, jump, interpolation, exponential, ternary — probes and windows drawn live
• Sorting: all six comparison sorts with sliding swap animations, plus counting, radix, and bucket sort
• Dynamic programming: knapsack, LCS, edit distance, LIS, coin change, rod cutting, subset sum, matrix chains, optimal BSTs — tables fill cell by cell with the exact dependencies shown
• Graphs: BFS, DFS, Dijkstra, Bellman-Ford, Floyd-Warshall, Prim, Kruskal with Union-Find, topological sort, SCCs, articulation points, and max flow
• Backtracking and branch & bound: N-Queens, Sudoku, Knight's Tour, Hamiltonian cycles, graph coloring, TSP with live pruning
• Strings, geometry, randomized and approximation algorithms, segment and Fenwick trees, and a P vs NP demonstration

Built for how people actually study

1. 1Pick a topic and algorithm — or land directly on its own page from search.
2. 2Feed it your own data: arrays, text and patterns, graph sizes, or a fresh random instance.
3. 3Auto-play at your speed, or click Next/Prev one operation at a time — stepping backward is exact.
4. 4Read the narration: every comparison shows a colored TRUE/FALSE verdict and a plain-English explanation.
