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 PYTHON3):

Solution:
l = int(input())
while l != 0:
	k = 0
	A = []
	B = []
	for l in range(0,l):
		li = input().split()
		if li[0] in A:
			i = A.index(li[0])
			B[i] = B[i] + (int(li[1]) * int(li[2]))
		else:
			A.append(li[0])
			B.append(int(li[1]) * int(li[2]))
	for j,b in enumerate(B):
		if b >= 10**6:
			print(A[j])
			k = 1
		
	if k == 0:
		print("NA")
	l = int(input())
