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…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 ItemNode

- How do you programmatically delete all occurrences of a key from a linked list?When deleting a node, why can’t you just use the delete operator to remove it from memory?Below you're given a Node class and a LinkedList class. You will implement a method for the LinkedList class named "delete48in148". That is, whenever there is a sequence of nodes with values 1, 4, 8, we delete the 4 and 8. For exCample, Before: 1 -> 4 -> 8 LAfter: 1 Before: 7 -> 1 -> 4 -> 8 -> 9 -> 4 -> 8 After: 7 -> 1 -> 9 -> 4 -> 8 Before: 7 -> 1 -> 4 -> 8 -> 4 -> 8 -> 4 -> 8 -> 9 After: 7 -> 1 -> 9 Note from the above example that, after deleting one instance of 48, there may be new instances of 148 formed. You must delete ALL of them. Requirement: Your implementation must be ITERATIVE (i.e., using a loop). You must NOT use recursion. Recursive solutions will NOT be given marks. import ... # No other import is allowed
- LINKED LIST IN PYTHON Create a program using Python for the different operations of a Linked List. Your program will ask the user to choose an operation. 1. Create a List -Ask the user how many nodes he/she wants. -Enter the element/s -Display the list -Back to menu 2. Add at beginning -Ask for the element to be inserted. -Display the list -Back to menu 3. Add after -Ask for the element to be inserted. -Ask for the position AFTER which the element is to be inserted -Display the list -Back to menu 4. Delete -Ask for the element (data) to be deleted -If found, delete the node with that data. -If multiple values, delete only the first element found -If not found, display that the element is not found -back to menu 5. Display -Display the list 6. Count -Display the number of elements 7. Reverse -Reverse the list and display it 8. Search -Ask the user for the element (data) to be searched -Display a message if the element is found or not 9. Quit -Exits the programThe hexadecimal values requested are in octal format.Given the doubly linked list: head tail 10 20 30 60 40 50 assuming that the Node class has three fields: prev, info, and link, what will be the list after performing the following operations?
