Solution: Convert Sorted Array to Binary Search Tree

Explore how to build a height-balanced binary search tree from a sorted array by recursively selecting middle elements as roots. Understand the process, implement the recursive algorithm, and analyze time and space complexities to solve this common tree construction problem.

We'll cover the following...

Statement

Given an array of integers, nums, sorted in ascending order, your task is to construct a height-balanced binary search tree (BST) from this array.

In a height-balanced BST, the difference of heights of the left subtree and right subtree of any node is not more than 1.

Note: There can be multiple valid BSTs for a given input.

Constraints:

...
