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...
https://leetcode.com/problems/balanced-binary-tree/ 题目: Given a binary tree, determine if it is height-balanced. every 思路: 根据结点高度,递归判断是否满足平衡树定义。此题跟Kth Smallest Element in a BST做法类似,在遍历过程中遇到满足某条件的结点时,将结果放到全局变量中,如果没遇到最终递归返回的...
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...
http://bangbingsyb.blogspot.com/2014/11/leetcode-balanced-binary-tree.html 我想说明的是,什么 depth of tree and height of tree depth of node n: length of path from n to root. 所以说, depth of subtree 指的应该就是 这棵subtree最大的深度,以该subtree结点为root。
