What line of code changes the
first diagram below to the second?
first:
second:
Select one:
a. tail->next = head;
b. head = head->next;
c. tail = head;
d. head = tail;
e. p = NULL;
Homework Answers
a) is the correct answer
tail->next=head; means the last node of the linked list points to the head node.i.e. 2nd image.
Other options are incorrect because:
b)head=head ->next; points to the 2nd node of the linked list to be the head.
c)tail=head; means the last node and first node are set equal.
d) head = tail; means the first node and last node are set equal.
e)p=NULL; This remains same as before i.e. 1st image

Given a singly linked list contains 5 nodes, which simply shows as 5->4->3->2->1, what is the value that you can find in the second node of the remaining list if the following statements are applied? Assume head reference refers the first node of the list. Node prev = head; Node curr = head. next; while(curr.next!=null) { if(prev.element > 3) { prev = curr; curr = curr.next; } else break; } head = prev.next; Question 3 options: 3 2 4 1...

Data Structures - Singly Linked Lists You will add a method swapNodes to SinglyLinkedList class (below). This method should swap two nodes node1 and node2 (and not just their contents) given references only to node1 and node2. The new method should check if node1 and node2 are the same node, etc. Write the main method to test the swapNodes method. You may need to traverse the list. package linkedlists; public class SinglyLinkedList<E> implements Cloneable { // ---------------- nested Node class...
