Hey everyone, in this video we break down the four types of rotations you need to know for AVL trees - self-balancing binary search trees. <br /><br />We cover single right rotations, single left rotations, double right rotations, and double left rotations with clear diagrams and explanations of the input patterns and how they become the balanced output pattern.<br /><br />If you've been learning about binary search trees and want to understand how AVL trees maintain their balance through rotations, this is the perfect next step. We look at the trinode subtrees, balance factors, and exactly how to rearrange the pointers for each case.<br /><br />Great for computer science students, coding interviews, or anyone building their data structures knowledge.<br /><br />Watch the full series on binary search trees and AVL trees for more.<br /><br />00:00 Introduction to AVL Tree Rotations<br />00:14 Previous Videos Overview<br />00:28 Balance Factors and Trinode Subtrees<br />00:50 Identifying Imbalance<br />01:56 When to Rotate<br />02:20 Four Input Patterns<br />02:41 Target Balanced Pattern<br />04:18 Single Right Rotation<br />04:33 Single Left Rotation<br />08:44 Double Rotations<br />11:51 Remembering Rotation Types<br />13:04 Wrapping Up Rotations<br />13:27 Thanks and Outro<br /><br />avl tree, avl rotations, single right rotation, single left rotation, double right rotation, double left rotation, self balancing binary search tree, binary search tree, data structures, tree rotations, avl tree tutorial, balance factor, computer science, algorithms, coding interview, bst<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 /><br />
