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 C (judge verdict: Time Limit Exceeded)

#include<stdio.h>


int main()
{
	int no[4000], pri[4000], num[4000], i=0,j,n;
	scanf("%d", &n);
	while (n) {
		scanf("%d %d %d", &no[i], &pri[i], &num[i]);
		i++;
		n--;
	}
	for (j = 0; j < i; i++) if (pri[j] * num[j] >= 100000) printf("%d\n", no[j]);
    return 0;
