The following function is supposed to take a list and return a copy of the list with the order of the elements reversed. However, it doesn't work as intended. Point out the problems, and explain how to fix them. public static List reverse (List 1st) { List rev; if (1st instanceof ArrayList){ rev = new ArrayListO: } else { rev - new Linkedlist(); } Iterator it - lst.list Iterator(1st.size()-1); while (it.hasPrevious()) { rev.add(1, it previous()); } return rev; }
