该算法的思路是基于Solution #1的一种改进,把每个节点的height信息和isBalanced信息融合到一起个变量中: 如果该变量>=0,那么该节点是balanced并且该变量就是节点的height; 如果该变量<0,那么该节点是unbalanced,但同时我们失去了它的height信息。 publicclassCheckTreeBalanced2 {publicintcheckHeight(TreeNode root){if...
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 ofeverynode never differ by more than 1. Example 1: Given the following tree[3,9,20,null,null,15,7]: 3 /...

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. 给定一个二叉树,确定它是高度平衡的。对于这个问题,一棵高度平衡的二叉树...
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衡二叉树 C++代码: class Solution{public:boolisBalanced(TreeNode*root){if(root==NULL){returntrue;}if(abs(maxDepth(root->left)-maxDepth(root->right))>1){returnfalse;}returnisBalanced(root->left)andisBalanced(root->right);}intma...
