剑指offer-二叉树镜像

题目描述

操作给定的二叉树，将其变换为源二叉树的镜像。 

输入描述:

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
public class Solution {public void Mirror(TreeNode root) {if (root == null) {return;}if (root.left == null && root.left == null) {return;}TreeNode temp = root.left;root.left = root.right;root.right = temp;if (root.left != null) {Mirror(root.left);}if (root.right != null) {Mirror(root.right);}}}
