Watch arrays, lists, and sorts step by step
Browser visualizers for a few data structures. Open one tool, change the input, watch the next step. Not a full DSA course — chapters live under Courses.
Array Explorer
Visualize how arrays work in memory. Master indexing, slicing, insertion, and deletion operations.
Linked List Studio
Understand pointers and nodes. Build singly and doubly linked lists and watch connections change in real-time.
Stack & Queue Lab
Explore LIFO and FIFO principles. Visualize push, pop, enqueue, and dequeue operations.
Sorting Arena
Compare sorting algorithms side-by-side. Watch Bubble, Merge, Quick, and Insertion sort in action.
Visual Learning
See exactly how algorithms process data step-by-step.
Interactive Code
Modify inputs and watch the code execution flow.
Complexity Analysis
Understand Big O notation with real-time metrics.
