Chapter 3, Problem 5R
Explanation of Solution
Consequences when delete the two lines from code:
Note: Refer Code Fragment 3.15 “SinglyLinkedList class definition” in the Text book.
The SinglyLinkedList class contains number of methods such as “size()”, “first()”, “last()”, “addFirst()”, “addLast()”, “removeLast()”, and “removeFirst()”.
In removeFirst() method,
- Remove the line number “51” and “52” in this method.
- That is, resetting the “tail” field to “null”.
Modified:
In the above code, just remove or delete the Line “51” and “52”. Then the code is given below:
//Method definition
public E removeFirst( ) //Line 46
{
//Check whether the linked list is empty
if (isEmpty( )) //Line 47
//Return null, there is no element to remove
return null;
/*Get the head node from linked list and assigned it. */
E answer = head.getElement( ); //Line 48
//Assign the head node as next node of head
head = head...

You are required to complete the LinkedList class. This class is used as a linked list that has many methods to perform operations on the linked list. To create a linked list, create an object of this class and use the addFirst or addLast or add(must be completed) to add nodes to this linked list. Your job is to complete the empty methods. For every method you have to complete, you are provided with a header, Do not modify those headers(method name, return type or parameters). You have to complete the body of the method.

Important: Make all your implementation in the same attached file and submit only one file in the
submission link.
Given the linked list data structure discussed in the lecture, implement a sub-class
TSortedList that makes sure that elements are inserted and maintained in an ascending
order in the list. So, given the input sequence {1,7,3,11,5}, when printing the list after
inserting the last element it should print like 1, 3, 5, 7, 11. Note that with inheritance, you
have to only care about the insertion situation as deletion should still be handled by the
parent class.
In the basic implementation, assume that you only have head which is a pointer to the
head of the list. Now, if we have both head and tail pointers, what improvements can be
done to speed up the insertion?
Add a new public member function to the LinkedList class named reverse() which reverses the items in the list. You must take advantage of the doubly-linked list structure to do this efficiently as discussed in the videos/pdfs, i.e. swap each node’s prev/next pointers, and finally swap headPtr/tailPtr. Demonstrate your function works by creating a sample list of a few entries in main(), printing out the contents of the list, reversing the list, and then printing out the contents of the list again to show that the list has been reversed.
Note: your function must actually reverse the items in the doubly-linked list, not just print them out in reverse order!
Note: we won't use the copy constructor in this assignment, and as such you aren't required to update the copy constructor to work with a doubly-linked list.
This is what I have so far but its not working!

- You may find a doubly-linked list implementation below. Our first class is Node which we can make a new node with a given element. Its constructor also includes previous node reference prev and next node reference next.

- 4 O T O I D06 It is time for you to demonstrate your skills in a project of your own choice. You must DESIGN, ANALYSE AND CODE any method for the GENERIC MyLinkedList class that will manipulate the linked list. You can decide yourself what it should be following the specification below: 1. Purpose: The method must make logical sense - it should be of some purpose to somebody. You should describe in the text who will use the method for which purpose. 2. Clearly explain the problem. Then clearly explain how your method will solve it. 3. Test program: Test the method using a wranned class like Integer l Filters Add a caption. > Status (Contacts)arrow_forwardThere’s a somewhat imperfect analogy between a linked list and a railroad train, where individual cars represent links. Imagine how you would carry out various linked list operations, such as those implemented by the member functions insertFirst(), removeFirst(), and remove(int key) from the LinkList class in this hour. Also implement an insertAfter() function. You’ll need some sidings and switches. You can use a model train set if you have one. Otherwise, try drawing tracks on a piece of paper and using business cards for train cars.arrow_forwardWrite a Java class myLinkedList to simulate a singly linked list using arrays as the underlying structure. Include the following methods: 1. insert an element within the linked list.(this should also work for the front and the rear of the list) 2. Remove an element from the linked list 3. Display (print) the elements of the linked list in order. 4. A method to check if the list is "empty". Test your solution using a linked list that initially has the characters A, B, D, E, F, and G. Insert "C" between B and D. Remove element "F". [Hint: One solution (recommended) is to use 2 arrays. One for the data, and the other for the "next" pointer. Also, consider using dummy nodes for the front, and possibly the rear of the list] Extend the solution so that it simulates a doubly linked list!
