#define P(a) printf("%d\n",a)

int main()

{

    int n, p, calc, l;

    while(S(n)==1)

    {

        if(n==0) break;

        l = (int)((log (n))/(log (2.0)));

        p = pow(2,l);

        calc = (n-p);

        if(p==n)

            P(n);

        else

            P(2*calc);

    }

    return 0;
