LeetCode 235. Lowest Common Ancestor of a Binary Search Tree - Interview Prep Ep 137

Why watch

A walkthrough of LeetCode 235, solving the Lowest Common Ancestor problem in a Binary Search Tree using the BST property where all left descendants are smaller and all right descendants are larger than the node value. This allows a more efficient O(h) solution compared to the general LCA problem. The video demonstrates both recursive and iterative approaches suitable for technical interviews.
