很迷的map,虽然很基础不过很迷
1 #include<bits/stdc++.h>
2 using namespace std;
3 int main(){
4 int N;cin>>N;
5 while(N--){
6 int n;cin>>n;
7 map<string,map<string,int> >mapp;
8 while(n--){
9 string p,f;
10 int num;
11 cin>>f>>p>>num;
12 mapp[p][f]+=num;
13 }
14 map<string,map<string,int> >::iterator i;
15 map<string,int>::iterator j;
16 for(i = mapp.begin(); i!=mapp.end();++i){
17 cout<<i->first<<endl;
18 for(j = i->second.begin();j!=i->second.end();++j){
19 cout<<" |----"<<j->first<<"("<<j->second<<")"<<endl;
20 }
21 }
22 if(N) cout<<endl;
23 }
24 return 0;
25 }
