104 - Maximum Depth of Binary Tree\. Easy 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 **Example 3:** **Input:** root = [] **Output:** 0 **Example 4:** **Input:** root = [0] **Output:** 1 **Constraints:** * The number of nodes in the tree is in the range [0, 104]. * `-100 <= Node.val <= 100`
