二叉树的深度-python

标签：pytho   节点   class   二叉树的深度   val   return   init   tree   pre   

思路：用递归思想，不停往下找节点，找到一个节点加1

# -*- coding:utf-8 -*-
# class TreeNode:
#     def __init__(self, x):
#         self.val = x
#         self.left = None
#         self.right = None
class Solution:
    def TreeDepth(self, pRoot):
        # write code here
        if pRoot == None:
            return 0
        left = self.TreeDepth(pRoot.left)
        right = self.TreeDepth(pRoot.right)
        return max(left, right) + 1
