Problem: There is data on sales of your company. Your task is to write a program which identifies good workers.

The program should read a list of data where each item includes the employee ID i, the amount of sales q and the corresponding unit price p. Then, the program should print IDs of employees whose total sales proceeds (i.e. sum of p × q) is greater than or equal to 1,000,000 in the order of inputting. If there is no such employees, the program should print "NA". You can suppose that n < 4000, and each employee has an unique ID. The unit price p is less than or equal to 1,000,000 and the amount of sales q is less than or equal to 100,000.



Input

The input consists of several datasets. The input ends with a line including a single 0. Each dataset consists of:


n (the number of data in the list)
i p q
i p q
:
:
i p q


Output

For each dataset, print a list of employee IDs or a text "NA"

Example

Input

4
1001 2000 520
1002 1800 450
1003 1600 625
1001 200 1220
2
1001 100 3
1005 1000 100
2
2013 5000 100
2013 5000 100
0


Output

1001
1003
NA
2013

Solution (in CPP):

Solution:
#include <iostream>
#include <vector>
#include <map>
using namespace std;
int find(vector<pair<int,long long> > &in,int n){
	for(int i=0;i<in.size();++i){
		if(in[i].first==n) return i;
	}
	return -1;
}
int main(){
	int n,num,price,amount;
	while(cin>>n&&n){
		vector<pair<int,long long> > v;
		while(n--){
			cin>>num>>price>>amount;
			if(find(v,num)!=-1) v[find(v,num)].second+=(long long)price*amount;
			else v.push_back(make_pair(num,(long long)price*amount));
		}
		bool f=false;
		for(vector<pair<int,long long> >::iterator it=v.begin();it<v.end();++it){
			if((*it).second>=1000000){
				cout<<(*it).first<<"\n";
				f=true;
			}
		}
		if(!f) cout<<"NA\n";
	}
	return 0;
}
