Below you're given a Node class and a LinkedList class. You will implement amethod for the LinkedList class named "delete48in148". That is, whenever thereis a sequence of nodes with values 1, 4, 8, we delete the 4 and 8. For exCample,Before: 1 -> 4 -> 8LAfter: 1Before: 7 -> 1 -> 4 -> 8 -> 9 -> 4 -> 8After: 7 -> 1 -> 9 -> 4 -> 8Before: 7 -> 1 -> 4 -> 8 -> 4 -> 8 -> 4 -> 8 -> 9After: 7 -> 1 -> 9Note from the above example that, after deleting one instance of 48, theremay 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 class Node:A node in the linked Listvalue: intnext: Optional (Node]definit_ (self, value: int, nx: Node = None):self.value = valueself.next = nxclass LinkedList:The LinkedList is empty if and only if self.head is Nonehead: Optional (Node]def init_(self, head: Optional [Node]):self.head = headdef delete48in148(self) -> None:In all occurrences of 148, delete the 48.TODO: complete this methodYour implementation must be ITERATIVE (1.e., using a loop).You must NOT use recursion.Recursive solutions will NOT be given marks.pass

JAVA please 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 Code provided in the assignment ItemNode.java:

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…
Given the interface of the Linked-List struct Node{ int data; Node* next = nullptr; }; class LinkedList{ private: Node* head; Node* tail; public: display_at(int pos) const; ... }; Write a definition for a method display_at. The method takes as a parameter integer that indicates the node's position which data you need to display. Example: list: 5 -> 8 -> 3 -> 10 display_at(1); // will display 5 display_at(4); // will display 10 void LinkedList::display_at(int pos) const{ // your code will go here }
Make a doubly linked list and apply all the insertion, deletion and search cases. The node willhave an int variable in the data part. Your LinkedList will have a head and a tail pointer.Your LinkedList class must have the following functions: 1) insert a node1. void insertNodeAtBeginning(int data);2. void insertNodeInMiddle(int key, int data); //will search for keyand insert node after the node where a node’s data==key3. void insertNodeAtEnd(int data);2) delete a node1. bool deleteFirstNode(); //will delete the first node of the LL2. bool deleteNode(int key); //search for the node where its data==keyand delete that particular node3. bool deleteLastNode(); //will delete the last node of the LL3) Search a node1. Node* searchNodeRef(int key); //will search for the key in the datapart of the node2. bool searchNode(int key); The program must be completely generic, especially for deleting/inserting the middle nodes. Implement all the functions from the ABOVE STATEMENTS and make a login and…
Given main.py and a Node class in Node.py, complete the LinkedList class (a linked list of nodes) in LinkedList.py by writing the insert_in_ascending_order() method that inserts a new Node into the LinkedList in ascending order. Ex: If the input is: 8 3 6 2 5 9 4 1 7 the output is: 1 2 3 4 5 6 7 8 9 Code given
Implement class “LinkedList” which has two private data members head: A pointer to the Node class length: length of the linked listImplement the following private method:1. Node* GetNode(int index) const;A private function which is only accessible to the class methods. . For example, index 0 corresponds to the head and index length-1 corresponds to end node of the linked list. The function returns NULL if the index is out of bound.Implement the following public methods:2. LinkedList();Constructor that sets head to NULL and length equal to zero.3. bool InsertAt(int data, int index);Insert a new node at the index. Return true if successful, otherwise,return false. The new node should be at the position “index” in the linked list after inserting it. You might have to use GetNode private function. these 3 parts

Implement a LinkedList class that stores integers using dynamic memory and a proper main program to test it. The following member functions need to be properly implemented and tested: 1. Default constructor. 2. Parmetrized Constructor. 3. Sum. 4. Average. 5. InsertAtHead. 6. InsertAtTail. 7. Delete. 8. Pop. 9. Circular. 10. Display. Sample answer is also provided.
You are going to implement a program that creates an unsorted list by using a linked list implemented by yourself. NOT allowed to use LinkedList class or any other classes that offers list functions. It is REQUIRED to use an ItemType class and a NodeType struct to solve this homework. The “data.txt” file has three lines of data 100, 110, 120, 130, 140, 150, 160 100, 130, 160 1@0, 2@3, 3@END You need to 1. create an empty unsorted list 2. add the numbers from the first line to list using putItem() function. Then print all the current keys to command line in one line using printAll(). 3. delete the numbers given by the second line in the list by using deleteItem() function. Then print all the current keys to command line in one line using printAll().. 4. putItem () the numbers in the third line of the data file to the corresponding location in the list. For example, 1@0 means adding number 1 at position 0 of the list. Then print all the current keys to command line in one…
