Data Structures & Algorithms Visualizer

Analyse algorithm time and space efficiencies using Big O boundary notations.

Explore sequential element access, subsegment manipulations, insertion, deletion, and 2D grid matrix walks.

Learn the Last-In, First-Out (LIFO) stack data structure with pushing, popping, and structural queries.

Understand the First-In, First-Out (FIFO) queue buffers, enqueueing, and dequeueing animations.

Visualize ring buffer queues optimizing index array space via circular wrap pointers.

Interact with double-ended queue insertion and deletion flows at both head and rear points.

Interact with linear chain node arrays, traversal, head/tail adjustments, and index operations.

Visualize node linkages referencing both previous and next pointers supporting bidirectional walks.

Understand node loops where the tail pointer links back to the head node to form a closed circle.

Contrast contiguous index array memory slots vs scattered linked node chains.

Explore hierarchical parent-child nodes, traversal modes (in-order, pre-order, post-order), and search lookups.

Observe recursive visiting orders (Inorder, Preorder, Postorder) over node trees.

Understand min and max heap properties, tree structure balance, and heapify up/down actions.

Visualize key hashing functions, index mapping arrays, and hash collision resolution techniques.
