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>
#define INT(name) int name; scanf("%d",&name);
#define VINT(name,n) vector<int> name(n); for(int i = 0;i < n;i++) scanf("%d",&name[i]);

using namespace std;

int main(int argc, char const *argv[]){
	vector<unsigned long long> data(4000);
	vector<int> f(4000);
	int i;
	long long a,b,c;
	bool check;

	cin >> i;
	while(i){

		for(int j = 0;j < 4000;j++){
			data[j] = 0;
		}


		for(int j = 0;j < i;j++){
			cin >> a >> b >> c;
			data[a - 1] += (long long)b * c;
			f[j] = a - 1;
		}


		check = false;

		for(int j = 0;j < i;j++){
			if(data[f[j]] >= 1000000){
				printf("%d\n",f[j] + 1);
				data[f[j]] = 0;
				check = true;
			}
		}

		if(!check) printf("NA\n");

		cin >> i;
	}

	return 0;
}
