这道题关于倒置树/镜像树的思路其实在1043 Is It a Binary Search Tree,关键就是通过不建树,改变子节点遍历顺序的方法来输出倒置顺序。 另外就是多了个查找根节点的环节,这个只要从头到尾逐个找就好了。 #include <iostream> #include <stdio.h> #include <queue> using namespace

输入一个正整数N(<=10),接着输入0~N-1每个结点的左右儿子结点,输出这颗二叉树的反转的层次遍历和中序遍历。 AAAAAccepted code: 1#defineHAVE_STRUCT_TIMESPEC2#include<bits/stdc++.h>3usingnamespacestd;4inta[17][5];5boolvis[15];6voidbfs(intr){7queue<int>q;8q.push(r);9cout<<r;10while(!

PAT 1102 Invert a Binary Tree (25分) 反转二叉树 使用递归思想反转二叉树是非常简单的,很容易能想到。写一个递归函数,第一步交换左子树与右子树。第二步分别递归左子树与右子树,即交换左子树的左子树与右子树,交换右子树的左子树和右子树,。。。如此层层递归直到达到设置的退出条件。 反转...
