- public LLNode secondHalf(LLNode head) { }Start this lab with the code listed below. The LinkedList class defines the rudiments of the code needed to build a linked list of Node objects. You will first complete the code for its addFirst method. This method is passed an object that is to be added to the beginning of the list. Write code that links the passed object to the list by completing the following tasks in order:1. Create a new Node object.2. Make the data variable in the new Node object reference the object that was passed to addFirst.3. Make the next variable in the new Node object reference the object that is currently referenced in variable first.4. Make variable first reference the new Node.Test your code by running the main method in the LinkedListRunner class below. Explain, step by step, why each of the above operations is necessary. Why are the string objects in the reverse order from the way they were added? public class LinkedList{ private Node first; public LinkedList() { first = null; } public Object…JAVA programming question i will attach images of the ourQueue code and the main I have to do the following: *create an ourQueue object, add the following sequence: *2,-3,4,-6,7,8,-9,-11 *create and ourStack object *write a program/ one loop that would result into the stack containing all of the negative number at the bottom and the positive numbers at the top. *outStack at the end should contain the following *[-3,-6,-9,-11,2,4,7,8]

In addition, BinarySearchArray will implement a static method testBinarySearchArray() that populates the lists, and lets the user interactively test the two classes by adding and removing elements. The parameter BinarySearch can represent either class and tells testBinarySearchArray which class to test. Steps to Implement: 1) To get started create a new project in IntelliJ called BinarySearch. Add a class to your project called BinarySearchArray. Then add another class BinarySearchArrayList and an interface called BinarySearch. The interface BinarySearch includes public method stubs as shown in the diagram. You are allowed to add BinarySearchArrayList to the same file as BinarySearch but don't add an access modifier to this class, or for easier reading, you can declare the classes in separate files with public access modifiers. Only the class…If the elements “A”, “B”, “C” and “D” are placed in a stack and are removed one at a time, in what order will they be removed?
- write a program for a library automation which gets the isbn number, name, author and publication year of the books in the library. the status will be filled by the program as follows: if publication year before 1985 the status is reference else status is available, the information about the books should be stored inside a linked list. the program should have a menu and the user inserts, displays, and deletes the elements from the menu by write a selecting options. the following data structure should be used. struct list char isbn[ 20 ]: char namei 20 ]. char authori 20 ]: int year; char status[200j: struct list "next, jinfo, wedoad n un posn ag pinogs nuu sulnogoj l press 1. to insert a book press 2. to display the book list press 3. to delete a book from listIt is python language Write the code that creates a new Node class. It will store data and next attributes. You only need to create the __init__ method. data and next variables will have default values, both set to None. Assume you are using the Node class from the previous connection to create a LinkedList. You have the code below, create a method that removes the first node from the LinkedList. class LinkedList: def __init__(self): self.head = None Based on the code from the last two questions, create a new LinkedList. Add 2 values to the LinkedList (there is an add method that accepts data as an argument, called add). Then call the removeFront method created in the previous question. Based on the previous questions, create a Queue class that uses the LinkedList for its data storage. Create the __init__, isEmpty, insert, remove, and size methods. Assume that LinkedList class has the add, removeFront and size methods defined. Based on the LinkedList code already…A map is a container that stores a collection of ordered pairs, each pair consists of a key and a value, <key, value>. Keys must be unique. Values need not be unique, so several keys can map to the same values. The pairs in the map are sorted based on keys. Group of answer choices True False
- Java Given main() in the ShoppingList class, define an insertAtEnd() method in the ItemNode class that adds an element to the end of a linked list. DO NOT print the dummy head node. Ex. if the input is: 4 Kale Lettuce Carrots Peanuts where 4 is the number of items to be inserted; Kale, Lettuce, Carrots, Peanuts are the names of the items to be added at the end of the list. The output is: Kale Lettuce Carrots Peanuts Second image is ItemNodeIn C++.When an element is removed from a queue, where is it removed from?
