Maximum Depth of Binary Tree

Explore how to calculate the maximum depth of a binary tree by following the longest path from root to leaf using depth-first search. This lesson helps you understand the problem constraints and implement an efficient O(n) time and space solution, enhancing your ability to solve tree traversal challenges in coding interviews.

Statement

You are given the root of a binary tree, and your task is to determine the maximum depth of this tree. The maximum depth of a binary tree is determined by the count of nodes found on the longest pathway from the root node to the farthest leaf node.

Constraints:

  • The number of nodes in the tree is in the range [1 ...
