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 JavaScript (judge verdict: Wrong Answer)

process.stdin.on("data",function(c){
	var k;
	(c+"").trim().split("\n").some(function(a){
		var f=0;
		if(+a==a){
			for(i in k){
				if(k[i]>=1e6){
					f=1;
					console.log(i);
				}
			}
			if(!f&&k){console.log("NA");}
			k={};
			return;
		}
		a=a.split(" ");
		k[a[0]]=(k[a[0]]||0)+(a[1]*a[2]);
	});
}).resume();
