Web5 apr. 2024 · 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. Web11 feb. 2024 · A balanced binary tree is defined as a binary tree in which at every node, its left sub-tree and right sub-tree have an equal height or their height differ by just 1. In other words, if we consider any node of the tree as the root of a tree, then the heights of its left sub-tree and right sub-tree should never differ by more than 1.

First of all, let’s think about the best node to put as the root. Since we need the tree to be balanced, we must put the middle value as the root. After that, we can add the values before the middle to the left of the tree.
