int shu(int);


int main(int argc, char *argv[])
{
    int a[10],b=0,max=0,d=0;
    while (cin>>a[b])
    {if (a[b]==0) break;
     b++;}
     while (1)
     {if (a[d]==0) break;
      while (a[d]>=0)
      {if (shu(a[d])>max) max=shu(a[d]);
       a[d]--;}
       cout<<max<<endl;
       d++;}

    system("PAUSE");
    return EXIT_SUCCESS;
}

  int shu(int n)
  {int c;
   if (n==0) c=0;
   else if (n==1) c=1;
   else if (n%2==0) c=shu(n/2);
   else c=shu((n-1)/2)+shu((n-1)/2+1);}
