Question

I need an example of how to swap and index within a doubly linked list with index + 1. This is written in java.

public class A3DoubleLL<E> {
   /*
   * Grading:
   * Swapped nodes without modifying values - 2pt
   * Works for all special cases - 1pt
   */
   public void swap(int index) {
       //swap the nodes at index and index+1
       //change the next/prev connections, do not modify the values
       //do not use delete/remove/insert/add to help with this process
       //make sure to account for all special cases
   }

   private Node start, end;
   private int count;
   public A3DoubleLL() {
       start = end = null;
       count = 0;
