What Makes a Tree 'Balanced'?
Explore the concept of height-balanced binary trees, focusing on how to check the height difference between left and right subtrees. Learn a step-by-step algorithm to identify balanced trees and practice applying this knowledge with examples relevant to coding interviews.
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.
