题意：判断两棵树是否是同一棵树。
解题思路：这题比较简单。用递归来做。首先判断两个根节点的值是否相同，如果相同，递归判断根的左右子树。
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 p, a tree node # @param q, a tree node # @return a boolean def isSameTree(self, p, q): if p == None and q == None: return True if p and q and p.val == q.val: return self.isSameTree(p.left, q.left) and self.isSameTree(p.right, q.right) return False
