unsigned int Func(unsigned int A, unsigned int B){
    if(A==0)
        return B;
    else
        return B+Func(A-1,B);
}

What does the above recursive function, written in c++, calculate ?

( A + 1 ) × B (A+1) \times B A × ( B − 1 ) A \times (B-1) ( A − 1 ) × B (A-1) \times B A × ( B + 1 ) A \times (B+1)
