Maximum Depth of Binary Tree

Explore how to determine the maximum depth of a binary tree by analyzing the longest root-to-leaf path. Learn to apply depth-first search methods and understand constraints and optimal complexity for this common coding interview problem.

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 path from the root node to the farthest leaf node.

Constraints:

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