here is my snippet: class D : public A, public B, public C {

int val;
public:
    //Initially val is 1
     D()
     {
        val = 1;
     }


     //Implement this function
     void update_val(int new_val)
     {
        while( val < new_val) {
            if(new_val % (2*val)==0){
                this->A::func(val);
            } else if(new_val % (3*val)==0) {
                this->B::func(val);
            }   else if ( new_val %(5*val)==0) {
                this->C::func(val);
            } else {
                break;
            }
        }

     }
