Elevator

Time Limit: 2 Seconds Memory Limit: 65536 KB

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

直接把物品加起来判断和限重的大小

#include <iostream>
#include <cstdio>
using namespace std;

int main()
{
   int T,n,m,sum,a;
   scanf("%d",&T);
   while(T--)
   {
       scanf("%d%d",&n,&m);
       int sum=0;
       for(int i=0;i<n;i++)
        scanf("%d",&a),sum+=a;
        if(sum<=m)
            printf("Safe\n");
        else
            printf("Warning\n");
   }
    return 0;
}
