题目描述:
操作给定的二叉树,将其变换为源二叉树的镜像。
代码
/*
struct TreeNode {
int val;
struct TreeNode *left;
struct TreeNode *right;
TreeNode(int x) :
val(x), left(NULL), right(NULL) {
}
};*/
class Solution {
public:
void Mirror(TreeNode *pRoot) {
if(pRoot!=NULL)
{
swap(pRoot);
Mirror(pRoot->left);
Mirror(pRoot->right);
}
}
void swap(TreeNode *pRoot)
{
static TreeNode *temp=NULL;
temp=pRoot->left;
pRoot->left=pRoot->right;
pRoot->right=temp;
}
};
