LeetCode刷题实战104:二叉树的最大深度
算法的重要性,我就不多说了吧,想去大厂,就必须要经过基础知识和业务逻辑面试+算法面试。所以,为了提高大家的算法能力,这个公众号后续每天带大家做一道算法题,题目就从LeetCode上面选 !
今天和大家聊的问题叫做 二叉树的最大深度,我们先来看题面:
https://leetcode-cn.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.
Note: A leaf is a node with no children.
题意
解题
class Solution {
public int maxDepth(TreeNode root) {
if (root == null) {
return 0;
}
return Math.max(maxDepth(root.left), maxDepth(root.right)) + 1;
}
}
