Assume that the following method is added to the class KWLinkedList. What does this method do?

public boolean question()

{

     if (size%2 == 1 || size < 2) return false;

     Node<E> h = head;

     for(int i = 0; i < size/2; i++)

              h=h.next;

     Node<E> p = head;

     while (h!= null)

     {

             if (! p.data.equals(h.data)) return false;

             p = p.next;

             h = h.next;

     }

    return true;
