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: Wrong Answer)


using System;
using System.Collections.Generic;
using System.Text;

class TEST{
    static void Main(){
		List<int> result = new List<int>();

		while (true)
		{
			int getNumber = int.Parse(Console.ReadLine());
			bool check = false;
			if (getNumber == 0) break;

			for (int i = 0; i < getNumber; i++)
			{
				String[] data = Console.ReadLine().Split(' ');
				int sNumber = int.Parse(data[0]);
				int sales =  (int.Parse(data[1]))*(int.Parse(data[2]));
				if (sales >10000){
					check = true;
					result.Add (sNumber);
				}
			}
			
			if (check == false){
				result.Add (0);
			}
		}

		foreach(int shain in result){
			if (shain == 0){
				Console.WriteLine("NA");
			}else{
				Console.WriteLine("{0}",shain);
			}
		}
	}
