111 - Minimum Depth of Binary Tree\. Easy Given a binary tree, find its minimum depth. The minimum depth is the number of nodes along the shortest path from the root node down to the nearest leaf node. **Note:** A leaf is a node with no children. **Example 1:**  **Input:** root = [3,9,20,null,null,15,7] **Output:** 2 **Example 2:** **Input:** root = [2,null,3,null,4,null,5,null,6] **Output:** 5 **Constraints:** * The number of nodes in the tree is in the range [0, 105]. * `-1000 <= Node.val <= 1000`
