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<bits/stdc++.h>
using namespace std;
int main()
{
    int n;
    while(cin>>n,n){
        bool flag=0;
        double result[4001]={};
        for(int i=0,str,ans=0;i<n;i++){
            double sale,num;
            cin>>str>>sale>>num;
            sale/=1000;num/=1000;
            result[str]+=sale*num;
            if(result[str]>=1){
                cout<<str<<endl;
                result[str]=-50;
                flag=1;
            }
        }
        if(!flag)cout<<"NA"<<endl;
    }
}
