VisuAlgo

Verified

Free algorithm visualization platform from National University of Singapore (NUS) covering 26+ data structures and algorithms. Provides step-by-step animated visualizations for sorting algorithms (Quick Sort, Merge Sort, Heap Sort), graph algorithms (Dijkstra, BFS, DFS, Kruskal, Prim), tree structures (BST, AVL, Red-Black, Segment Tree), and dynamic programming problems. Used by 2M+ computer science students globally for exam preparation (CS1020, CS2040, CS3230), coding interview prep (FAANG companies), and algorithm complexity analysis (Big-O notation). Each visualization includes pseudocode, time complexity breakdown, and interactive mode for custom input. Created by Dr. Steven Halim and maintained by NUS School of Computing. Alternative to Algorithm Visualizer, USFCA Visualization Tool, and Sorting.at.

🎓 Optimal Learning Path for CS Students

1. Start with VisuAlgo: When learning algorithms in CS courses (CS1020, CS2040, CS3230), use VisuAlgo to understand HOW algorithms work step-by-step. Watch Quick Sort split arrays, see Dijkstra's algorithm find shortest paths, visualize AVL tree rotations. Free forever, no signup required.

2. Practice with LeetCode: After understanding algorithm logic, practice implementation on LeetCode's 2500+ problems. Essential for coding interviews at FAANG companies (Google, Meta, Amazon, Apple, Netflix). Start with Easy problems, progress to Medium/Hard.

3. Assess with HackerRank: Use HackerRank for skill certification and company-specific assessments. Many employers use HackerRank tests in their hiring process. Free for students.
