文章目录一、题目1.1 题目描述 操作给定的二叉树,将其变换为源二叉树的镜像。 1.2 题目链接二、实现代码/**
public class TreeNode {
int val = 0;
TreeNode left = null;
TreeNode right = null;
public TreeNode(int val) {
this.val = val;
}
}
*/
public class Solution {
public void Mirror(TreeNode root) {
if(root == null) return;
TreeNode node = root.left;
root.left = root.right;
root.right = node;
Mirror(root.left);
Mirror(root.right);
}
}
