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 ofeverynodenever differ by more than 1. 代码: /** * Definition for a binary tree node. * struct TreeNode { *...
(a)和(b)都是排序二叉树,但是查找(b)的93节点就需要查找6次,查找(a)的93节点就需要查找3次,所以(b)的效率不高。 平衡二叉树(Balanced Binary Tree 或 Height-Balanced Tree)又称AVL树。它或者是一颗空树,或者是具有下列性质的二叉树:它的左子树和右子树的深度只差的绝对值不超过1。若将二叉树上节点的平...

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)...
For this problem, a height-balanced binary tree is defined as a binary tree in which the depth of the two subtrees ofeverynode never differ by more than 1. Hide Tags Tree Depth-first Search 思路:平衡二叉树就是和数的高度有关系,例外,如果有不是平衡二叉树的子...
A Balanced Binary Tree is a type of binary search tree where the height of the tree is proportional to log base 2 of the number of elements it contains. This balanced structure ensures efficient searching, with elements being found by inspecting at most a few nodes. ...

Forthisproblem, 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. 2.解法分析 判断一个树是否为平衡二叉树与求树的深度如出一辙,只是返回值有两个,一个是当前树是否为平衡二叉树,另一个是当前树的高度。
