[编程题]排名
- 热度指数：4100 时间限制：C/C++ 1秒，其他语言2秒 空间限制：C/C++ 64M，其他语言128M
- 算法知识视频讲解
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。
输入描述:
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。
输出描述:
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。

优先队列，过关的入队，最后输出队列大小再一个个吐出来
#include <bits/stdc++.h>
using namespace std;
int main()
{
auto cmp=[](pair<string,int> p1,pair<string,int> p2){return p1.second==p2.second?p1.first>p2.first:p1.second<p2.second;};
int n,m,g;
while(cin>>n>>m>>g)
{
vector<int> scores(m+1);
for(int j=1;j<=m;++j)cin>>scores[j];
priority_queue<pair<string,int>,vector<pair<string,int> >,decltype(cmp)> students(cmp);
for(int i=0;i<n;++i)
{
pair<string,int> p("s",0);
cin>>p.first;
int num;
cin>>num;
for(int j=0;j<num;++j)
{
int no;
cin>>no;
p.second+=scores[no];
}
if(p.second>=g)students.push(p);
}
cout<<students.size()<<endl;
while(!students.empty())

return 0;

出题的人是有多无聊

while(num--)

}
if(buf[j].score>=g) count++;
}
