    108 - Convert Sorted Array to Binary Search Tree.

    Easy

    Given an integer array nums where the elements are sorted in ascending order , convert it to a height-balanced binary search tree.

    A height-balanced binary tree is a binary tree in which the depth of the two subtrees of every node never differs by more than one.

    Example 1:

    Input: nums = [-10,-3,0,5,9]

    Output: [0,-3,9,-10,null,5]

    Explanation: [0,-10,5,null,-3,null,9] is also accepted:

    Example 2:

    Input: nums = [1,3]

    Output: [3,1]

    Explanation: [1,3] and [3,1] are both a height-balanced BSTs.

    Constraints:

    • 1 <= nums.length <= 104
    • -104 <= nums[i] <= 104
    • nums is sorted in a strictly increasing order.
