100. Same Tree
Given two binary trees, write a function to check if they are equal or not.
Two binary trees are considered equal if they are structurally identical and the nodes have the same value.
题目大意:
判断两个二叉树是否完全相同。包括他们节点的内容。
代码如下:(递归版)
/**
* 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:
bool isSameTree(TreeNode* p, TreeNode* q) {
bool childResult;
if( NULL == p && NULL == q)
return true;
if( NULL != p && NULL != q && p->val == q->val)
{
return childResult = isSameTree(p->left,q->left) && isSameTree(p->right,q->right);
}
return false;
}
