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. 此题是经典的求二叉树深度深度题目,可采用递归的方式,以此求每个节点的左子树深度和右子树深度,然后返回该节点左右子树深度最大的那个即为该节点的深度 具体代码如下: /** * Defi…
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. Have you met this question in a real interview? Yes Example Given a binary tree as follow:…
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. 求二叉树的最大深度问题用到深度优先搜索DFS,递归的完美应用,跟求二叉树的最小深度问题原理相同.代码如下: C++ 解法一: class Solution { public: in…
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. 方法一: 层次遍历,整棵树的层数,即二叉树的最大深度.主体的代码还是在层次遍历的基础上改成的. /** * Definition for binary tree * struct…
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 [,,,,], / \ / \ 方法一:采用…
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. Note: A leaf is a node with no children. Example: Given binary tree [3,9,20,null,null,1…
Given a binary tree, find its minimum depth. The minimum depth is the number of nodes along the shortest path from the root node down to the nearest leaf node. Hide Tags Tree Depth-first Search 这题是找二叉树的最小深度,这是广度搜索比较好吧,为啥提示给的是 深度优先呢. 判断树是否为空 将ro…
