    1006 - Hex-a-bonacci
    Time Limit: 0.5 second(s) Memory Limit: 32 MB

    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.

    第一便是WA,两个没搞定,,一个是MOD,还有竟然从0case开始了。。。
     
    罪过。。
    直接上AC代码了。
