The row numbermshould be equal to the height of the given binary tree. The column numbernshould always be an odd number. The root node's value (in string format) should be put in the exactly middle of the first row it can be put. The column and the row where the root node belongs...
Given the root of a binary tree, return its maximum depth.A binary tree's maximum depth is the number of nodes along the longest path from the root node down to the farthest leaf node. 英文版地址 leetcode.com/problems/m 中文版描述 给定一个二叉树,找出其最大深度。二叉树的深度为根节点到...
空间复杂度:O(Height),Height为树的最大深度 官方版 class Solution { int ans; public int diameterOfBinaryTree(TreeNode root) { ans = 1; depth(root); return ans - 1; } public int depth(TreeNode node) { if (node == null) { return 0; // 访问到空节点了,返回0 } int L = depth(...
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...
