How time flies! The graduation of this year is around the corner. N members of ZJU ACM/ICPC Team decided to hold a party in a restaurant. The restaurant is located in a skyscraper
so they need to take an elevator to reach there.

The elevator's maximum load is M kilograms. The weight of the i-th team member is A_i kilograms. If the total weight of people in the elevator exceeds
the maximum load of the elevator, the elevator will raise the alarm and will not move.

Please write a program to implement the weight detector of the elevator.

Input

There are multiple test cases. The first line of input is an integer T indicates the number of test cases. For each test case:

The first line contains two integers N (1 <= N <= 20) and M (1 <= M <= 2000). The next line contains N integers A_i (1
<= A_i <= 500).

Output

For each test case, output "Safe" if no alarm will be raised. Otherwise, output "Warning".

Sample Input

2
3 800
50 60 70
9 800
50 55 60 60 60 60 65 70 360

Sample Output

Safe
Warning
