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.Scanner;
public class Main{
	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		while(sc.hasNext()){
			int s = sc.nextInt();
			if(s == 0) break;
			int[] n = new int[s];
			int[] p = new int[s];
			int[] q = new int[s];
			int[] sells = new int[s];
			boolean[] judge = new boolean[s];
			int count = 0;

			for(int i= 0; i < s; i++){
				n[i] = sc.nextInt();
				p[i] = sc.nextInt();
				q[i] = sc.nextInt();
				if(i >= 1){
					if(p[i] == p[i-1] && q[i] == q[i-1]){
						judge[i] = false;
					}
				}
				sells[i] = p[i] * q[i];
				if(sells[i] >= 1000000){
					judge[i] = true;
					count++;
				}else{
					judge[i] = false;
				}
			}

			for(int i = 0; i < s; i++){
				if(judge[i]){
					System.out.println(n[i]);
				}
			}

			if(count == 0) System.out.println("NA");
