Solution: Convert Sorted Array to Binary Search Tree

Discover how to construct a height-balanced binary search tree from a sorted array by applying a recursive depth-first search technique. This lesson helps you understand selecting the middle element as the root and recursively building balanced left and right subtrees, ensuring minimal height difference and efficient tree structure.

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:
