Binary Trees β€” Insert, Search, AVL Balance

Audience: Software EngineerCategory: Computer Science

Description

Demonstrates binary search tree operations step by step: inserting nodes to build a BST, searching for a value with left/right comparisons shown, detecting an unbalanced tree, and performing an AVL left rotation to restore balance. Height and balance factor labels update throughout.

Binary Trees β€” Insert, Search, AVL Balance

Description

Demonstrates binary search tree operations step by step: inserting nodes to build a BST, searching for a value with left/right comparisons shown, detecting an unbalanced tree, and performing an AVL left rotation to restore balance. Height and balance factor labels update throughout.

Phases

# Phase Name Duration Description
1 Intro 3s Title displayed
2 BST Insert 18s Insert nodes 5,3,7,1,4,6,8 one by one; show comparison path for each
3 BST Search 8s Search for value 4; highlight comparison at each node, path shown in cyan
4 Imbalance Detection 5s Show an unbalanced tree (right-heavy), highlight balance factors in red
5 AVL Rotation 10s Animate left rotation to rebalance; show height labels updating
6 Outro 4s Balanced tree displayed with all balance factors = 0 or Β±1
