AVL Insertion

Explore AVL tree insertion and understand how to maintain balance through rotations in four distinct cases. Learn key concepts like nodes involved in imbalances and the process to rebalance an AVL tree efficiently with O(log n) time complexity.

Introduction

Insertion in AVL trees is done the same way that BST insertion is done. However, when a node is inserted into a BST, it usually becomes unbalanced, i.e., the tree has a node that has a left-right subtree height difference greater than 1. So, AVL ...
