How to Perform AVL Tree Rotations - Step By Step Example

In this video we walk through a real example of maintaining an AVL tree by performing a rotation. We start with an unbalanced tree, compute balance factors, identify the Z Y and X nodes, and apply a double right rotation to restore balance. Perfect follow-up if you've seen the basics of binary search trees and AVL trees. Watch as we turn an invalid AVL tree into a perfectly balanced one with clear step-by-step instructions. If you're learning data structures and algorithms, this practical example will help you understand when and how to rotate. 00:00 Introduction to AVL Tree Rotation 00:14 Prerequisites and Previous Videos 00:36 AVL Trees Overview 00:40 Types of Rotations and Balance Factors 01:01 Examining the Example Tree 01:24 Confirming Binary Search Tree Properties 01:27 Computing Balance Factors 01:39 Identifying Imbalance at Node 65 02:01 Locating the Z Node 02:54 Finding Y and X Nodes 04:08 Assigning X Y Z Values 04:33 Creating ABC In-Order Representation 04:58 Drawing the Target Rotation Pattern 05:34 Updating Node Values in Pattern 06:04 Checking Unaccounted Children 07:00 Reattaching Nodes and Performing Rotation 07:56 Recomputing Balance Factors 08:24 Updating Root Balance Factor 08:41 Resulting Perfectly Balanced Tree 08:48 Identifying Double Right Rotation 09:06 Explaining the Rotation Process 10:16 Conclusion and Next Video Teaser 11:56 Channel Promotion and Outro 15:48 Final Hello and Recap =-=-=-=-=-=-=-=-= Thanks for watching!
