(一)题目
来源:https://leetcode.com/problems/maximum-depth-of-binary-tree/
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.
(二)解题
题目大意:求二叉树的最大深度
解题思路:采用深度优先搜索,很容易求出最大深度
/**
* Definition for a binary tree node.
* struct TreeNode {
* int val;
* TreeNode *left;
* TreeNode *right;
* TreeNode(int x) : val(x), left(NULL), right(NULL) {}
* };
*/
class Solution {
public:
int max;//用来保存最大深度值
int maxDepth(TreeNode* root) {
max = 0;
dfsTree(root,0);//深度优先搜索递归
return max;
}
void dfsTree(TreeNode* root , int dep)
{
if(dep>max) max=dep;//记录最大深度值
if(root==NULL) return;
dfsTree(root->left,dep+1);//遍历左子树
dfsTree(root->right,dep+1);//遍历右子树
}
};
