8. Linked Lists Fill in the "code" column in the following table providing a solution that will turn the "before" picture into the "after" picture by modifying links between the nodes shown. You are not allowed to change any existing node's data field value and you are not allowed to construct any new nodes, but you are allowed to declare and use variables of type ListNode (oftern called "temp" variables). You are limited to at most two variables of type ListNode for each of the four subproblems below. You are writing code for the ListNode class as shown below: public class ListNode public int data; // data stored in this node public ListNode next; //link to next node in the list As in the LinkedList lab, all lists are terminated by null and the variables p and q have the value null when they do not point to anything
