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.<br /><br />Watch as we turn an invalid AVL tree into a perfectly balanced one with clear step-by-step instructions.<br /><br />If you're learning data structures and algorithms, this practical example will help you understand when and how to rotate.<br /><br />00:00 Introduction to AVL Tree Rotation<br />00:14 Prerequisites and Previous Videos<br />00:36 AVL Trees Overview<br />00:40 Types of Rotations and Balance Factors<br />01:01 Examining the Example Tree<br />01:24 Confirming Binary Search Tree Properties<br />01:27 Computing Balance Factors<br />01:39 Identifying Imbalance at Node 65<br />02:01 Locating the Z Node<br />02:54 Finding Y and X Nodes<br />04:08 Assigning X Y Z Values<br />04:33 Creating ABC In-Order Representation<br />04:58 Drawing the Target Rotation Pattern<br />05:34 Updating Node Values in Pattern<br />06:04 Checking Unaccounted Children<br />07:00 Reattaching Nodes and Performing Rotation<br />07:56 Recomputing Balance Factors<br />08:24 Updating Root Balance Factor<br />08:41 Resulting Perfectly Balanced Tree<br />08:48 Identifying Double Right Rotation<br />09:06 Explaining the Rotation Process<br />10:16 Conclusion and Next Video Teaser<br />11:56 Channel Promotion and Outro<br />15:48 Final Hello and Recap<br /><br />avl tree, avl tree rotation, binary search tree, data structures, self balancing tree, tree rotation, double rotation, balance factor, avl tree example, computer science, algorithms, bst, coding tutorial<br /><br />=-=-=-=-=-=-=-=-=<br /><br />Thanks for watching!<br /><br />Find us on other social media here:<br />- https://www.NeuralLantern.com/social<br />- Twitter / X: https://x.com/NeuralLantern<br />- Rumble: https://rumble.com/c/c-3696939<br />- BitChute: https://www.bitchute.com/channel/pg1Pvv5dN4Gt<br />- Daily Motion: https://www.dailymotion.com/neurallantern<br />- Minds: https://www.minds.com/neurallantern/<br />- Odysee: https://odysee.com/@NeuralLantern:5<br /><br />Please show your support!<br /><br />- Buy me a coffee: https://ko-fi.com/neurallantern<br /><br />- Subscribe + Sharing on Social Media<br />- Leave a comment or suggestion<br />- Subscribe to the Blog: https://www.NeuralLantern.com<br />- Watch the main "pinned" video of this channel for offers and extras<br />
