Maximum Depth of Binary Tree– LeetCode Problem

**Problem:**

Given the `root`

of a binary tree, return *its maximum depth*.

A binary tree’s **maximum depth** is the number of nodes along the longest path from the root node down to the farthest leaf node.

**Example 1:**

Input:root = [3,9,20,null,null,15,7]Output:3

**Example 2:**

Input:root = [1,null,2]Output:2

**Constraints:**

- The number of nodes in the tree is in the range
`[0, 10`

.^{4}] `-100 <= Node.val <= 100`
