For this problem, a height-balanced binary tree is defined as:a binary tree in which the left and right subtrees of every node differ in height by no more than 1. 英文版地址 leetcode.com/problems/b 中文版描述 给定一个二叉树,判断它是否是高度平衡的二叉树。本题中,一棵高度平衡二叉树定义...
The space complexity of this solution is O(n), where n is the number of nodes in the tree. This is because we are recursively constructing the tree and maintaining call stack space for each node. In the worst case, the recursion depth would be equal to the height of the tree, which ...
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. 题目分析: 平衡二叉树:(1)要么为空,要么左右子树的深度差值不超过1;(2)左右两个子树都是一棵平衡二叉树,即子树也都要都满足条件(1...
Balanced Binary Tree (Easy) 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 1: Given the following tree [3,...
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. 【解答】checkBalanced 方法用来递归检查是否平衡的,返回树高度,偷了个巧,如果发现不平衡抛出 TreeUnbalancedException 异常: 代码语言:javasc...
