题目：http://vj.bit-studio.cn/contest/209424#problem/C

方法：本来用把产地与水果名字用结构体包装起来，然后再把数量与结构体map起来，纠结于map怎么排序，后来发现用结构体更容易

代码：

#include<iostream>
#include<map>
#include<cstdio>
#include<cstdlib>
using namespace std;
typedef struct flu

    char name[81];
    char place[81];

bool cmp(const flue&f1, const flue&f2) {
    return f1.name > f2.name;
}
int main()
{
    int n;
    scanf("%d", &n);
    for (int l = 0; l < n; l++)
    {
        if (l != 0)cout << endl;
        int m;
        scanf("%d", &m);
        flue *fff=new flue [m];
        for (int j = 0; j < m; j++)
        {
            flue temp;
            scanf("%s", temp.name);
