Problem:
Sale Result

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"

Sample 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 for the Sample Input

1001
1003
NA
2013

Solution in JAVA (judge verdict: Wrong Answer)

import java.util.*;

class Main
{
	public static void main(String[] args)
	{
		Scanner sc = new Scanner(System.in);

		while(true)
		{
			
			
			int n = sc.nextInt();
			int count = 0;
			//一つも社員番号が出力されなかった場合に(T)が実行されます.
			
			if ( n == 0 ) break;

			for ( int i = 0; i < n; i++ )
			{
				int dg = Integer.parseInt(sc.next());
				int tanka = Integer.parseInt(sc.next());
				int num = Integer.parseInt(sc.next());

				int total = tanka * num;

				if ( total >= 1000000 ) {
					System.out.println(dg);
					count += 1;
				}
				
			}
			
			if ( count == 0 ) System.out.println("NA"); //(T)

		}

	}
