操作给定的二叉树,将其变换为源二叉树的镜像。
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 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; } if (root != null){ TreeNode temp = root.right; root.right = root.left; root.left = temp; } if (root.left!=null){ Mirror(root.left); } if(root.right!=null){ Mirror(root.right); } } }
