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.

Mutated Minions Codechef Solution

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.


  • 1 ≤ T ≤ 100
  • 1 ≤ N ≤ 100
  • 1 ≤ K ≤ 100
  • All initial characteristic values lie between 1 and 105, both inclusive.


5 10
2 4 1 35 1



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.

Mutated Minions Codechef Solution in C++

void solve_test()
    int n, k, current;
    cin >> n >> k; 
    int arr[n];
    int i;
    for (i = 0; i < n; i++)    cin >> arr[i];
    int result = 0;
    for (i = 0; i < n; i++)
        current = arr[i] + k;
        if (current % 7 == 0)
    cout << result << endl;

int main() {
    int t;
    cin >> t;
    while (t--)
    return 0;
