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<stdio.h>

int main(void) {
	long long int a, b, count = 1, number = 0, syain[4010], tanka[4010], suuryou[4010], score[4010] = {}, noruma = 1000000, sens = 0;
	while (count) {
		sens = 0;
		long long int score[4010] = {};
		scanf("%d", &count);
		for (size_t i = 0; i < count; i++)
		{
			scanf("%lld %lld %lld", &syain[number], &tanka[number], &suuryou[number]);
			score[syain[number]] += tanka[number] * suuryou[number];
			if (score[syain[number]] >= noruma)
			{
				printf("%lld\n", syain[number]);
				sens++;
			}
			number++;
		}
		if (sens == 0 && count != 0)
		{
			printf("NA\n");
		}
	}
	return 0;
