109 - Convert Sorted List to Binary Search Tree\. Medium Given the `head` of a singly linked list where elements are **sorted in ascending order** , convert it to a height balanced BST. For this problem, a height-balanced binary tree is defined as a binary tree in which the depth of the two subtrees of _every_ node never differ by more than 1. **Example 1:**  **Input:** head = [-10,-3,0,5,9] **Output:** [0,-3,9,-10,null,5] **Explanation:** One possible answer is [0,-3,9,-10,null,5], which represents the shown height balanced BST. **Example 2:** **Input:** head = [] **Output:** [] **Example 3:** **Input:** head = [0] **Output:** [0] **Example 4:** **Input:** head = [1,3] **Output:** [3,1] **Constraints:** * The number of nodes in `head` is in the range [0, 2 * 104]. * -105 <= Node.val <= 105
