Problem
Gru has not been in the limelight for a long time and is, therefore, planning something particularly nefarious. Frustrated by his minions' incapability which has kept him away from the limelight, he has built a transmogrifier — a machine which mutates minions.
Each minion has an intrinsic characteristic value (similar to our DNA), which is an integer. The transmogrifier adds an integer K to each of the minions' characteristic value.
Gru knows that if the new characteristic value of a minion is divisible by 7, then it will have Wolverine-like mutations.
Given the initial characteristic integers of N minions, all of which are then transmogrified, find out how many of them become Wolverine-like.
Input Format:
The first line contains one integer, T, which is the number of test cases. Each test case is then described in two lines.
The first line contains two integers N and K, as described in the statement.
The next line contains N integers, which denote the initial characteristic values for the minions.
Output Format:
For each testcase, output one integer in a new line, which is the number of Wolverine-like minions after the transmogrification.
Constraints:
- 1 ≤ T ≤ 100
- 1 ≤ N ≤ 100
- 1 ≤ K ≤ 100
- All initial characteristic values lie between 1 and 105, both inclusive.
Example
Input: 1 5 10 2 4 1 35 1Output: 1
Explanation:
After transmogrification, the characteristic values become {12,14,11,45,11}, out of which only 14 is divisible by 7. So only the second minion becomes Wolverine-like.
Program :

public static void main(String[] args)
{
Scanner in = new Scanner(System.in);
int t,n,i,k,j,m,l;
int a[]=new int[101];
t=in.nextInt();
for(i=0;i<t;i++)
{
j=0;
n=in.nextInt();
k=in.nextInt();
for(l=0;l<n;l++)
a[l]=in.nextInt();
for(m=0;m<n;m++)
{
if((a[m]+k)%7==0)
j++;
}
System.out.println(j);
}
in.close();
}
}
