Given a binary tree, find its maximum depth. The maximum depth is the number of nodes along the longest path from the root node down to the farthest leaf node. Note: A leaf is a node with no children. Example: Given binary tree [3,9,20,null,null,15,7…

Given a binary tree, find its maximum depth. The maximum depth is the number of nodes along the longest path from the root node down to the farthest leaf node. Note: A leaf is a node with no children. Example: Given binary tree [3,9,20,null,null,15,7…

Given a binary tree, find its maximum depth. The maximum depth is the number of nodes along the longest path from the root node down to the farthest leaf node. 题目标签:Tree 这道题目给了我们一个二叉树,要我们找到最大深度,就是从root点到最深的那个点之间点的数量.利用post order 来遍历二叉树,对于每一个点,它的两个chi…

Problem: Given a binary tree, find its maximum depth. The maximum depth is the number of nodes along the longest path from the root node down to the farthest leaf node. 初看本题第一印象为递归写法.首先找出终止条件:node == NULL.若未进入递归终止状态,则分左子树和又子树进行递归,最终返回累加最大的值.其代码如下: /*…

Given a binary tree, find its maximum depth. The maximum depth is the number of nodes along the longest path from the root node down to the farthest leaf node. 求树的高度. 深度优先搜索遍历.递归实现. /** * Definition for a binary tree node. * public class TreeNode { *…

题目描述: Given a binary tree, find its maximum depth. The maximum depth is the number of nodes along the longest path from the root node down to the farthest leaf node. 解题思路: 分左子树和右子数递归调用. 代码如下: /** * Definition for a binary tree node. * public class Tr…

Given a binary tree, find its maximum depth. The maximum depth is the number of nodes along the longest path from the root node down to the farthest leaf node. 分析:求二叉树的最大深度 解法一:很容易想到的便是递归(深度优先搜索) (1)如果根节点是空,则返回0:否则转到(2) (2)  l = 左子树的最大深度; r = 右子树的最大深…

题目: Given a binary tree, find its maximum depth. The maximum depth is the number of nodes along the longest path from the root node down to the farthest leaf node. 求二叉树的深度,递归一下就可以求到了. python新手(我)发现python中没有三元运算符,不过可以用true_part if condition else false…
