LeetCode 235: Lowest Common Ancestor of a Binary Search Tree | Python | Interview Question|Hack Code

Показать описание

In this video, we dive deep into Binary Search Trees (BSTs) and reveal how to find the Lowest Common Ancestor (LCA) of two given nodes using Python. We cover both recursive and iterative approaches, ensuring you understand the logic and implementation thoroughly. This tutorial is perfect for those preparing for coding interviews or anyone looking to enhance their knowledge of data structures.

We start with a brief overview of BST properties, followed by a step-by-step explanation of the algorithms, complete with visual aids and flowcharts. You'll also see a detailed dry run of the examples to solidify your understanding.
