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>
using namespace std;
int main(){
long long n,a,b,c,f,i,j,k,s[4001],aa[4001];
while(cin>>n){
if(n==0)break;
for(i=0;i<n;i++){s[i]=0;aa[i]=0;}
for(i=0;i<n;i++){
cin>>a>>b>>c;
k=i;
for(j=0;j<i;j++)if(a==aa[j]){k=j;break;}
aa[i]=a;
for(j=0;j<c;j++){
if(s[k]>=1000000)break;
s[k]+=b;
}
}
for(f=0,i=0;i<n;i++)
if(s[i]>=1000000){cout<<aa[i]<<endl;f=1;}
if(f==0)cout<<"NA"<<endl;
}
return 0;
