Hello there. In this video we break down exactly how to delete nodes from a binary search tree. We cover all three cases step by step: deleting a leaf node with zero children, deleting a node with one child by promoting it, and the trickiest case - deleting a node with two children using the in-order successor method.<br /><br />You'll see clear diagram walkthroughs, pointer manipulation explanations, and time complexity discussion for each type of removal. Perfect for computer science students, coding interview prep, or anyone strengthening their data structures knowledge.<br /><br />We search for the node, identify its children, and handle the reconnection properly to maintain the BST properties. Includes examples for each scenario and tips for implementing in code.<br /><br />If you're learning BST insert, search, and now removal, this completes the core operations.<br /><br />00:00 Introduction to BST Deletions<br />00:10 BST Review and Setup<br />00:46 Three Types of Deletions<br />00:56 Deleting a Leaf Node (Zero Children)<br />03:21 Pointer Manipulation for Leaf Deletion<br />05:25 Deleting a Node with One Child<br />07:17 Pointer Updates for One Child Deletion<br />10:09 Deleting a Node with Two Children<br />12:08 In-Order Traversal and Successor Concept<br />13:18 Finding In-Order Successor<br />14:20 Copying Successor Value and Recursive Delete<br />18:28 Deleting the Root Node Example<br />22:56 Additional One Child Successor Example<br />25:12 Time Complexity Summary<br />26:08 Closing and Outro<br /><br />binary search tree, bst deletion, delete node bst, binary search tree remove, bst remove node, inorder successor, data structures tutorial, binary tree deletion, cs data structures, coding interview, tree algorithms, bst operations<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
