Sorted Array To Balanced BST | InterviewBit Are you sure you want to create this branch? It can be seen that the middle element of the array forms the root of a balanced binary search tree, and the elements to the left of the array form the left sub-tree of the balanced BST and . We do this recursively to construct the balanced binary search tree. Given an array A[] of size N, sorted in ascending order. Sorted Array to Balanced BST By Finding The middle element The idea is to find the middle element of the array and make it the root of the tree, then perform the same operation on the left subarray for the root's left child and the same operation on the right subarray for the root's right child.
