【解題想法】多鍵值排序

• 採購需求表的需求項目，可能包含空白字元。需用 getline(cin, name); 讀入資料。
```#include <iostream>
#include <algorithm>
using namespace std;

struct Company{
int id, check;
double quote;
string name;
};

bool cmp(Company a, Company b){
if (a.check != b.check) return a.check > b.check;
else if (a.quote != b.quote) return a.quote < b.quote;
else return a.id < b.id;
}

int main() {
int n, p, Case = 1;
string s;
while (cin >> n >> p){
getline(cin, s); //clear buffer
if (n == 0 && p == 0) break;
for (int i = 0; i < n; i++)
getline(cin, s);
string name;
int check;
double quote;
Company company[p];
for (int i = 0; i < p; i++){
getline(cin, name);
cin >> quote >> check;
getline(cin, s); //clear buffer
company[i] = {i, check, quote, name};
for (int j = 0; j < check; j++)
getline(cin, s);
}
sort(company, company+p, cmp);
cout << "RFP #" << Case++ << "\n";
cout << company[0].name << "\n\n";
}
return 0;
}
