☐ Question 7 5 pts In Lab 8, consider the implementation of method swap(). First, consider the corner case where the nodes to be swapped are adjacent as shown below. Assume that both nodes I and J to be swapped exist in the linked list. To perform swapping correctly, we have to find the following nodes first in another methods. A: the node before I. If I is the list head, then A=null; ⚫ B: the ode after I. In this corner case, B==J. • X: the node before J. In this corner case, X==I. • Y: the node after J. If J is the list tail, then Y==null; Below is the graph that illustrates how to implement this method. head tail J 3 7 head A z 3 tail 7 B Z Give the codes according to the above illustration. Fill in the missing pieces. • If (head==1) head. • If (J.next==null) tail = b ; ; If (A!=null) A.next J.next • I.next = _d_ _e_; Hints: • Check method swap in the lab partial answer keys here: answer. Linked List.java • Follow the instructions at the top of the program file. Plug in your answers and see if the program output is the same as the expected. a b [Choose] [Choose] [Choose] d [Choose ] [Choose ] 20 a b с [Choose ] [Choose ] [Choose ] d [Choose ] [Choose ] f [Choose ] Question 8 (Cont.)
