Milestone 1 — Now Live

Core Data Structures

The building blocks of every algorithm. Visualize how data is organized, connected, and traversed — from simple linked nodes to self-balancing trees.

Linear Structures

Elements organized sequentially. Linked Lists, Stacks, and Queues form the foundation of memory-efficient data handling with pointer-based navigation.

Hierarchical Trees

Non-linear structures enabling O(log n) search. Binary Search Trees organize data for fast lookups, while Tries excel at prefix-based string operations.

Self-Balancing

AVL Trees and Heaps guarantee consistent performance by automatically rebalancing on every insert or delete — no worst-case O(n) traversals.

Interactive Visualizers

Linear DS

Linked Lists

Visualize pointers and nodes as they are added, removed, and searched in an interactive singly linked list with full pointer animations.

  • Head/tail pointer tracking
  • Insert at any index
  • In-place reversal animation
Insert O(1) Search O(n) Delete O(1)
Linear DS

Stack & Queue

Master LIFO and FIFO principles with an interactive dual-mode visualizer. Switch between Stack and Queue with a single click.

  • LIFO push/pop for Stack
  • FIFO enqueue/dequeue for Queue
  • Live top/front value tracking
Push/Enqueue O(1) Pop/Dequeue O(1)
Priority Queue

Binary Heap

Learn how Max/Min Heaps maintain their property through array-based tree structures with animated heapify operations.

  • Max & Min heap toggle
  • Step-by-step heapify up/down
  • Array ↔ tree dual view
Insert O(log n) Extract O(log n) Peek O(1)
Self-Balancing

AVL Tree

Observe how self-balancing trees perform rotations (LL, RR, LR, RL) to maintain O(log n) performance on every operation.

  • All 4 rotation types animated
  • Live balance factor per node
  • Tree height tracking
Insert O(log n) Delete O(log n) Search O(log n)
String Algo

Trie (Prefix Tree)

Explore how prefix trees store dictionary strings for efficient searching and autocompletion with character-by-character traversal.

  • Word insertion with path highlight
  • Prefix search with glow animation
  • Word bank chip display
Insert O(L) Search O(L) Space O(A×N)
Hierarchical

Binary Search Tree

Learn tree insertion, searching, and traversal logic visually with hierarchical nodes and animated in-order / pre-order / post-order results.

  • Insert, delete, search animations
  • 3-mode traversal selector
  • Min / max value tracking
Insert O(log n)* Search O(log n)* Worst O(n)
