The following is a module with functions which demonstrates how to convert a sorted array to a binary search tree using C#.


1. Sorted Array To BST – Problem Statement

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:

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 1

Example 2:

Example 2


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


2. Sorted Array To BST – Solution

The following is a solution which demonstrates how to convert a sorted array to a binary search tree.

QUICK NOTES:
The highlighted lines are sections of interest to look out for.

The code is heavily commented, so no further insight is necessary. If you have any questions, feel free to leave a comment below.

Once compiled, you should get this as your output for the example cases:


[0,-10,5,null,-3,null,9]
[1,null,3]
