二叉树的镜像定义:源二叉树 8 / 6 10 / \ / 5 7 9 11 镜像二叉树 8 / 10 6 / \ / 11 9 7 5
/* 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){ return ; } TreeNode *pTempt=pRoot->left; pRoot->left=pRoot->right; pRoot->right=pTempt; Mirror(pRoot->left); Mirror(pRoot->right); } };
递归实现,终止条件为叶子节点
