上代码

#include "iostream"
#include "cstdio"
#include "map"
#include "vector"
using namespace std;
map<string,vector<int> >v;
int main()
{
	int n;scanf("%d",&n);
	for(int i=1;i<=n;i++){int m;scanf("%d ",&m);string s;for(int j=1;j<=m;j++){cin>>s;v[s].push_back(i);}}
	int q;scanf("%d",&q);
	for(int i=1;i<=q;i++){
	string s;cin>>s;int k=v[s][0];printf("%d ",k);
	for(int j=1;j<v[s].size();j++){
	if(v[s][j]==k)continue;
	printf("%d ",v[s][j]);k=v[s][j];	
	}
	printf("\n");	
	}
	return 0;
}
