- Code Restructuring: Methods for Linked List operations are given. Restructure the codes to improve performance of codes. Linked List is a part of the Collection framework present in java.util package, however, to be able to check the complexity of Linked List operations, we can recode the data structure based on Java Documentation https://docs.oracle.com/javase/8/docs/api/java/util/LinkedList.html Instruction 1: Two (2) Java classes are provided, first, the Linked List class and second, the Linked List interface. On the Linked List class, check the comments, analyze then try to recode the said method/s. Post the changes in your code, if any. package com.linkedlist; public class LinkedList<E> implements ListI<E>{ //The Node Object signatures and constructor class Node<E>{ E data; Node<E> next; public Node(E obj) { data=obj; next=null; } }…Define the function (doubleBubbleLst lst). This function should resolve to a list of sublists, where each sublist holds a single element from lst and all sublists from lst are also bubbled, so that every list and sublist has no atoms. This is the deep recursion version of bubbleLst. For example: (doubleBubbleLst '(1 2 (3 4)) ) resolves to '((1) (2) (( (3) (4) ))).Binary Search Tree Implementation(Java)In the binary search tree implementation, which is completely unrelated to the linked list implementation above, you will use an unbalanced binary search tree. Since duplicates are allowed, each node will have to store a singly-linked list of all the entries that are considered identical. Two values are identical if the comparator returns 0, even if the objects are unequal according to the equals method. A sketch of the private representation looks something like this: private Comparator<? super AnyType> cmp;private Node<AnyType> root = null; private void toString( Node<AnyType> t, StringBuffer sb ){ ... the recursive routine to be called by toString ... } private static class Node<AnyType>{private Node<AnyType> left;private Node<AnyType> right;private ListNode<AnyType> items; private static class ListNode<AnyType>{private AnyType data;private ListNode<AnyType> next; public ListNode( AnyType d,…
- (Implement a doubly linked list) The MyLinkedList class used in Listing 24.6 is a one-way directional linked list that enables one-way traversal of the list. Modify the Node class to add the new data field name previous to refer to the previous node in the list, as follows:public class Node<E> { E element; Node<E> next; Node<E> previous;public Node(E e) { element = e; } }Implement a new class named TwoWayLinkedList that uses a doubly linked list to store elements. The MyLinkedList class in the text extends MyAbstractList. Define TwoWayLinkedList to extend the java.util.AbstractSequentialList class. You need to implement all the methods defined in MyLinkedList as well as the methods listIterator() and listIterator(int index). Both return an instance of java.util. ListIterator<E>. The former sets the cursor to the head of the list and the latter to the element at the specified index.Programming Exercise 8 asks you to redefine the class to implement the nodes of a linked list so that the instance variables are private. Therefore, the class linkedListType and its derived classes unorderedLinkedList and orderedLinkedList can no longer directly access the instance variables of the class nodeType. Rewrite the definitions of these classes so that these classes use the member functions of the class nodeType to access the info and link fields of a node. Also write programs to test various operations of the classes unorderedLinkedList and orderedLinkedList. template <class Type>class nodeType{public:const nodeType<Type>& operator=(const nodeType<Type>&);//Overload the assignment operator.void setInfo(const Type& elem);//Function to set the info of the node.//Postcondition: info = elem;Type getInfo() const;//Function to return the info of the node.//Postcondition: The value of info is returned.void setLink(nodeType<Type>…(IntelliJ) Write an easier version of a linked list with only a couple of the normal linked list functions and the ability to generate and utilize a list of ints. The data type of the connection to the following node can be just Node, and the data element can be just an int. You will need a reference (Java) or either a reference or a pointer (C++) to the first node, as well as one to the last node. * Create a method or function that accepts an integer, constructs a node with that integer as its data value, and then includes the node to the end of the list. If the new node is the first one, this function will also need to update the reference to the first node. This function will need to update the reference to the final node. Consider how to insert the new node following the previous last node, and keep in mind that the next reference for the list's last node should be null. * Create a different method or function that iteratively explores the list, printing the int data values as…
- Project 2: Singly-Linked List The purpose of this assignment is to assess your ability to: ▪Implement sequential search algorithms for linked list structures ▪Implement sequential abstract data types using linked data ▪Analyze and compare algorithms for efficiency using Big-O notation For this assignment, you will implement a singly-linked node class. Use your singly-linked node to implement a singly-linked list class that maintains its elements in ascending order. The SinglyLinkedList class is defined by the following data: ▪A node pointer to the front and the tail of the list Implement the following methods in your class: ▪A default constructor list<T> myList ▪A copy constructor list<T> myList(aList) ▪Access to first elementmyList.front() ▪Access to last elementmyList.back() ▪Insert value myList.insert(val) ▪Remove value at frontmyList.pop_front() ▪Remove value at tailmyList.pop_back() ▪Determine if emptymyList.empty() ▪Return # of elementsmyList.size() ▪Reverse order of…For this assignment, you need to implement link-based List and derivative ADTs in Java. To complete this, you will need the following: A LinkNode structure or class which will have two attributes - a data attribute and a pointer attribute to the next node. The data attribute of the LinkNode should be the Money class of Lab 1. A Singly Linked List class which will be composed of three attributes - a count attribute, a LinkedNode pointer/reference attribute pointing to the start of the list and a LinkedNode pointer/reference attribute pointing to the end of the list. Since this is a class, make sure all these attributes are private. The attribute names for the Node and Linked List are the words in bold in #1 and #2. For the Linked List, implement the most common linked-list behaviors as explained in class - getters/setters/constructors/destructors for the attributes of the class, (a) create new list, (b) add data, (c) delete data, (d) find data, (e) count of data items in the…7.
