What Makes a Tree 'balanced'?
Explore the concept of height-balanced binary trees and learn how to determine if a tree meets the balance condition where the height difference between left and right subtrees is at most one. Understand this fundamental idea through step-by-step algorithms and examples, helping you prepare for coding interviews involving tree data structures in C++.
Introduction
A binary tree is height-balanced if, for each node in the tree, the difference between the height of the right subtree and the left subtree is at most one.
