[leetcode]Maximum Depth of Binary Tree @ Python
原题地址:https://oj.leetcode.com/problems/maximum-depth-of-binary-tree/
题意:
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:求树的最大深度。使用递归,很简单。
代码:
# Definition for a binary tree node # class TreeNode: # def __init__(self, x): # self.val = x # self.left = None # self.right = None class Solution: # @param root, a tree node # @return an integer def maxDepth(self, root): if root == None: return 0 else: return max( self.maxDepth(root.left), self.maxDepth(root.right) ) + 1
