        List<Integer> l = new LinkedList<>();
        l.add(0);
        l.add(1);
        ListIterator it = l.listIterator();
        while (it.hasNext()) {
            Integer elem = (Integer)it.next();
            it.add(100);
            System.out.print(elem + " ");
        }
        System.out.println();
        for (int i : l) {
            System.out.print(i + " ");
        }
