           ring.key = j;
           ring.next  = first;
           first   = ring;
       }
           last.next = first;
           return last;
   }

public void suicide()
   {
       Node reference = circle(A);
       while (reference != reference.next) //when there are still
more than 1 person
       for (int i = 1; i < B; i++)//you can still execute the B
person
       reference = reference.next;
       System.out.println( "-R.I.P # "+ reference.next.key );
       reference.next = reference.next.next;
