Add support for a ListIterator to the MyLinkedList class, as was done in Exercise 3.13.
Add support for a ListIterator to the MyArrayList class. The ListIterator interface in java.util has more methods than are shown in Section 3.3.5. Notice that you will write a listIterator method to return a newly constructed ListIterator, and further, that the existing iterator method can return a newly constructed ListIterator. Thus you will change ArrayListIterator so that it implements ListIterator instead of Iterator. Throw an UnsupportedOperationException for methods not listed in Section 3.3.5.
