HDU 1236 排名(结构体+排序)

今天的上机考试虽然有实时的Ranklist,但上面的排名只是根据完成的题数排序,没有考虑 
每题的分值,所以并不是最后的排名。给定录取分数线,请你写程序找出最后通过分数线的 
考生,并将他们的成绩按降序打印。 

Input测试输入包含若干场考试的信息。每场考试信息的第1行给出考生人数N ( 0 < N 
< 1000 )、考题数M ( 0 < M < = 10 )、分数线(正整数)G;第2行排序给出第1题至第M题的正整数分值;以下N行,每行给出一 
名考生的准考证号(长度不超过20的字符串)、该生解决的题目总数m、以及这m道题的题号 
(题目号由1到M)。 
当读入的考生人数为0时,输入结束,该场考试不予处理。 
Output对每场考试,首先在第1行输出不低于分数线的考生人数n,随后n行按分数从高 
到低输出上线考生的考号与分数,其间用1空格分隔。若有多名考生分数相同,则按他们考 
号的升序输出。

CS000000000000000002 20

Hint

Huge input, scanf is recommended.
#include<iostream>
#include<cstdio>
#include<cstring>
#include<algorithm>
using namespace std;
#define N 1010
int que[15];

struct node
{
	char str[22];
	int num;
	int score;
}stu[N];

bool cmp(const node &a, const node &b)
{
	if(a.score == b.score)
		return strcmp(a.str, b.str) < 0 ? 1 : 0; //按字典序升序
	else
		return a.score > b.score;
}

int main()
{
	int student, question, judge, x, count;
	while(scanf("%d", &student) && student)
	{
		count = 0;
		for(int i = 1; i <= student; ++i)
		{
			stu[i].score = 0;
			stu[i].num = 0;
		}
		scanf("%d%d", &question, &judge);
		for(int i = 1; i <= question; ++i)
			scanf("%d", &que[i]);
		for(int i = 1; i <= student; ++i)
		{
			scanf("%s%d", stu[i].str, &stu[i].num);
			while(stu[i].num--)
			{
				scanf("%d", &x);
				stu[i].score += que[x];
			}
			if(stu[i].score >= judge)
					count++;
		}
		sort(stu + 1, stu + 1 + student, cmp);
		printf("%d
", count);
		for(int i = 1; i <= student; ++i)
		{
			if(stu[i].score >= judge)
				printf("%s %d
", stu[i].str, stu[i].score);
			else
				break;
		}
	}
	return 0;
}
