Lowest Common Ancestor of a Binary Tree

Understand how to find the lowest common ancestor of any two nodes in a binary tree by practicing problem-solving with depth-first search. Learn to identify descendants and apply constraints to implement effective solutions.

We'll cover the following...

Statement

Given the root node of a binary tree with nn nodes, your task is to find the lowest common ancestor of two of its nodes, p and q.

Note: The lowest common ancestor of two nodes, ...
