Given a binary tree, determine if it isheight-balanced. 给定一个二叉树,判断它是否是高度平衡的二叉树。 Example 1: Input: root = [3,9,20,null,null,15,7] Output: true Example 2: Input: root = [1,2,2,3,3,null,null,4,4] Output: false Example 3: Input: root = [] Output: true...
Given a binary tree, determine if it is height-balanced. For this problem, a height-balanced binary tree is defined as: a binary tree in which the depth of the two subtrees of every node never differ by more than 1. Example Example 1: Given the following tree[3,9,20,null,null,15,...
