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<iostream>
#include<string>
using namespace std;
long long a[5000];
bool check[5000];
int main(){
	int n;
	while(true){
	cin>>n;
	if(n==0)
		break;
	for(int i=0;i<5000;i++){
		a[i]=0;
		check[i]=true;
	}
	bool na=true;
	long long b,c,d;
	for(int i=0;i<n;i++){
		cin>>b>>c>>d;
		a[b]+=c*d;
		if(a[b]>=1000000&&check[b]==true){
			check[b]=false;
			na=false;
			cout<<b<<endl;
		}
	}
	if(na==true)
		cout<<"NA"<<endl;
	}
	return 0;
}
