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>
using namespace std;

#define rep(i,n) for(int i=0; i<n; i++)
#define ll long long

int main()
{
    while (1)
    {
	int n,f=0,id,f2[4001];
	ll price,num,p[4001];
	rep(i,4001){p[i]=0;f2[i]=0;}
	cin >> n;
	if (n==0)break;
	rep(i,n)
	{
	    cin >> id >> price >> num;
	    p[id]+=price*num;
	    if (p[id] >= 1000000 && f2[id]==0)
	    {
		cout << id << endl;
		f=1;
		f2[id]=1;
	    }
	}
	if (f==0)cout << "NA" << endl;
    }
    return 0;
}
