DSA visualizers
Step through an array, list, or sort in the browser.
Four visualizers for common structures and sorts. Change the input, press next, watch the structure update. Full written DSA chapters live under Courses.
- ArraysIndex, slice, insert, and delete with a memory-style view
- Linked listsNodes and pointers for singly and doubly linked lists
- Stack & queuePush, pop, enqueue, and dequeue with LIFO / FIFO labels
- SortingBubble, insertion, merge, and quick sort step playback
What these tools are for
Seeing the next pointer move or the next swap fire. Not a full interview course. Use them alongside problem practice when a structure still feels abstract.
