Data Structures

CSE220

Abstract data types with their pointers, capacities and edge cases made visible.

Push, pop and peek against a fixed capacity, with overflow and underflow shown explicitly.

Enqueue and dequeue while front and rear move independently down the array.

See exactly when front and rear wrap around, and how full is told apart from empty.

Insert, delete and traverse while every next pointer is redrawn as it changes.

Track prev and next together through insertion and deletion at both ends.

Insert and delete nodes, then run in-order, pre-order, post-order and level-order traversals.

Place nodes and edges, and watch the adjacency list and adjacency matrix update together.

Insert, search and delete with node splits and merges animated at each level.
