If there is more than one answer, return **any of them**. A binary search tree is **balanced** if the depth of the two subtrees of every node never differs by more than `1`. **Example 1:**  **Input:** root = [1,null,2,null,3,null,4,null,null] **Output:** [2,1,3,null,null,null,4] **Explanation:** This is not the only correct answer, [3,1,4,null,2] is also correct. **Example 2:**  **Input:** root = [2,1,3] **Output:** [2,1,3] **Constraints:** * The number of nodes in the tree is in the range [1, 104]. * 1 <= Node.val <= 105
