http://poj.org/problem?id=2367 题意:给你n个数,从第一个数到第n个数,每一行的数字代表排在这个行数的后面的数字,直到0. 这是一个特别裸的拓扑排序的一个题目,拓扑排序我也是刚刚才接触,想法还是挺简单的.实现起来也不复杂. #include <stdio.h> #include <string.h> ],n; ][]; int topsort() { ;i<=n;i++) ;j<=n;j++) //遍历n次,找到第一个度为0的点,度为0的点…

题目链接:http://poj.org/problem?id=2367 题意: 知道一个数n, 然后n行,编号1到n, 每行输入几个数,该行的编号排在这几个数前面,输出一种符合要求的编号名次排序. 拓扑排序: 先找入度为0的点,再根据这个点删掉与之相连的点之间的弧,入度减一. #include <stdio.h> ][]; ]; int main() { int n; scanf("%d",&n); ;i<=n;i++) { int to; while(sca…

题目链接 http://poj.org/problem?id=2367 题意就是给定一系列关系,按这些关系拓扑排序. #include<cstdio> #include<cstring> #include<queue> #include<vector> #include<algorithm> using namespace std; ; int ans; int n; int in[maxn]; //记录入度 int num[maxn]; //记…

今天网易的笔试,妹的,算法题没能A掉,虽然按照思路写了出来,但是尼玛好歹给个测试用例的格式呀,吐槽一下网易的笔试出的太烂了. 就一道算法题,比较石子重量,个人以为解法应该是拓扑排序. 就去POJ找了道拓扑排序的题:POJ2367 直接上代码吧: #include<stdio.h> #include<string> #define clr(x) memset(x,0,sizeof(x)) ][]; ]; ]; using namespace std; int main() { int…

火星人的血缘关系很奇怪,一个人可以有很多父亲,当然一个人也可以有很多孩子.有些时候分不清辈分会产生一些尴尬.所以写个程序来让n个人排序,长辈排在晚辈前面. 输入:N 代表n个人 1~n 接下来n行 第i行表示第i个人的孩纸,无序排列,可能为空.0代表一行输入结束. (大概我的智商真的不合适,否则怎么这么久了连个拓扑排序都写不好,T了三次..) 代码: /******************************************** Problem: 2367 User: Memory:…
