Solution: Convert Sorted Array to Binary Search Tree

Explore how to transform a sorted array into a height-balanced binary search tree by applying recursive depth-first search. Understand the process of selecting the middle element as the root and recursively building balanced subtrees. This lesson helps you master constructing BSTs with minimal height differences and analyze the related time and space complexities.

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:
