平衡二叉树(Balanced Binary Tree) 平衡二叉树是一种特殊的二叉搜索树,它具有以下特点: 每个节点的左子树和右子树的高度差不超过1。 所有的子树也都是平衡二叉树。 通过保持平衡性,平衡二叉树可以在最坏情况下仍然具有较好的性能,保证查找、插入和删除操作的时间复杂

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. 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)...
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. 示例1: 输入:root = [3,9,20,null,null,15,7] 输出:true 示例2: ...

Balanced Binary Tree Easy 给定二叉树,判断其是否为平衡树。 Solution: 什么是平衡树? 空树平衡,非空二叉树满足下面条件时为平衡: 左分支平衡 右分支平衡 左右分支树的高度差不大于1 此题最直接的想法是从根节点往下,比较每个节点的左右深度,如果每个节点都是平衡的那么整棵树就是平衡的,这个方法是top-bottom的...
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. 思路: 用两个递归,一个递归找出树的最大深度,用另一个递归判断是否是平...
平衡二叉树 (Balanced Binary Tree) 所有的叶子结点到根结点的距离之差不超过一个定值,增删结点后可能会通过“旋转”再次平衡。 AVL树 (AVL Tree) 它是一棵平衡二叉搜索树,且它的左右两个子树的高度差不超过 1,并且左右两个子树都是一棵 AVL 树。
