二维map

#include<bits/stdc++.h>
using namespace std;

int main()
{
    int t;
    scanf("%d",&t);
    for(int cas=0;cas<t;cas++)
    {
        map<string,map<string,int> >p;
        map<string,map<string,int> >::iterator it;
        map<string,int>::iterator kk;
        int n;
        scanf("%d",&n);
        string name,place;
        int num;
        for(int i=0;i<n;i++)
        {
            cin>>name>>place>>num;
            ///string不能用%s
            p[place][name]+=num;
        }
        for(it=p.begin();it!=p.end();it++)
        {
            cout<<it->first<<endl;
            for(kk=it->second.begin();kk!=it->second.end();kk++)
            {
               cout<<"   |----"<< kk->first <<"("<< kk->second <<")"<<endl;
            }
        }
        if(cas!=t-1)
        printf("\n");
    }
    return 0;
}
