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

typedef pair<int, long long> pil;

bool cmp(pil lhs, pil rhs)
{
	return (lhs.first < rhs.first);
}

int main()
{
	int n;
	while (cin >> n, n){
	
	vector<pil> p(n);
	
	int cnt = 0;
	for (int i = 0; i < n; i++){
			int a, b, c;
			bool f = true;
			cin >> a >> b >> c;
			for (int j = 0; j <= cnt; j++){
				if (p[j].first == a){
					p[j].second += b * c;
					f = false;
				}
			}
			if (f){
				p[cnt].first += a;
				p[cnt].second += b * c;
				cnt++;
			}
		}
		bool fl = true;
		for (int i = 0; i < cnt; i++){
			if (1000000 <= p[i].second){
				cout << p[i].first << endl;
				fl = false;
			}
		}
		if (fl){
			cout << "NA" << endl;
		}
	}
	return (0);
