Binary Search Tree Removals - Delete Nodes with 0, 1, or 2 Children

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. 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. 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. If you're learning BST insert, search, and now removal, this completes the core operations. 00:00 Introduction to BST Deletions 00:10 BST Review and Setup 00:46 Three Types of Deletions 00:56 Deleting a Leaf Node (Zero Children) 03:21 Pointer Manipulation for Leaf Deletion 05:25 Deleting a Node with One Child 07:17 Pointer Updates for One Child Deletion 10:09 Deleting a Node with Two Children 12:08 In-Order Traversal and Successor Concept 13:18 Finding In-Order Successor 14:20 Copying Successor Value and Recursive Delete 18:28 Deleting the Root Node Example 22:56 Additional One Child Successor Example 25:12 Time Complexity Summary 26:08 Closing and Outro =-=-=-=-=-=-=-=-= Thanks for watching!
