Example Code Ch 13-2
Assume that a linked list is implemented using the Node class where a Node contains instance data of int info; and Node next; where next references the next Node in the linked list. Also assume that head references the first Node in the list.
-Refer to Example Code Ch 13-2: Assume Node temp references the last element of the linked list. Which of the following conditions is true about temp?
A) (temp.info == 0)
B) (temp.next == null)
C) (temp == head)
D) (temp == null)
E) (temp.next == null && temp.info == null)

If temp references the last element of the linked list, then its "next" instance variable would be null because there is no next element in the list. Option A is specific to the values stored in the node, and we have no information about those. Option C is unlikely as head typically references the first element in the list not the last. Option D is possible if the list is empty. Option E refers to both the info and next instance variables being null which is also unlikely.
