Given a code (not optimized), and necessary inputs, you have to find the output of the code for the inputs. The code is as follows:

int a, b, c, d, e, f;

int fn( int n ) {

if( n == 0 ) return a;

if( n == 1 ) return b;

if( n == 2 ) return c;

if( n == 3 ) return d;

if( n == 4 ) return e;

if( n == 5 ) return f;

return( fn(n-1) + fn(n-2) + fn(n-3) + fn(n-4) + fn(n-5) + fn(n-6) );

}

int main() {

int n, caseno = 0, cases;

scanf("%d", &cases);

while( cases-- ) {

scanf("%d %d %d %d %d %d %d", &a, &b, &c, &d, &e, &f, &n);

printf("Case %d: %d\n", ++caseno, fn(n) % 10000007);

}

return 0;

}

Input

Input starts with an integer T (≤ 100), denoting the number of test cases.

Each case contains seven integers, a, b, c, d, e, f and n. All integers will be non-negative and 0 ≤ n ≤ 10000 and the each of the others will be fit into a 32-bit integer.

Output

For each case, print the output of the given code. The given code may have integer overflow problem in the compiler, so be careful.
