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:
while True:
    input_n = int(input())
    key = 0
    if input_n == 0:
        break
    id_list = [[0 for i in range(2)]for i in range(input_n)]
    for i in range(input_n):
        id_line = input().split()
        for j in id_list:
            if j[0] == int(id_line[0]):
                j[1] += int(id_line[1]) * int(id_line[2])
                uriage = j[1]
                break
        else:
            id_list[i][0] = int(id_line[0])
            id_list[i][1] = int(id_line[1]) * int(id_line[2])
            uriage = id_list[i][1]
        if uriage >= 1000000:
            key = 1
    
    for i in id_list:
        if key == 0:
            print("NA")
            break
        if i[1] >= 1000000:
            print(i[0])
