- Create a class Stack. This stack will be implemented using the LinkedList class that has been provided. This stack will hold values of a generic type (<T>). Your Stack should have the following public methods: public void push(int n) public T pop() public T peek() public T size() public boolean isEmpty() public class LinkedList <T> { private Node head; private Node tail; private int size; public LinkedList() { head = null; tail = null; size = 0; } public void append(T data) { Node newNode = new Node(data); if (head == null) { head = newNode; } else { tail.next = newNode; } tail = newNode; size++; } public void prepend(T data) { Node newNode = new Node(data); if (head == null) { head = newNode; tail = newNode; } else { newNode.next = head; head = newNode; } size++; } public T getHead() { return head.data; } public T getTail() { return tail.data; } public int size() { return size; } public void removeByValue(T data) { Node current = head; while…Removes the element with key k if it exists. The position of current is// unspecified after calling this method.The first element of the returned pair // indicates whether k was removed, and the second is the number of key// comparisons made.Pair<Boolean, Integer> remove(K key); // Returns all keys of the map as a list sorted in increasing order. List<K> getAll(); } write this method javaIn python. Write a LinkedList class that has recursive implementations of the add and remove methods. It should also have recursive implementations of the contains, insert, and reverse methods. The reverse method should not change the data value each node holds - it must rearrange the order of the nodes in the linked list (by changing the next value each node holds). It should have a recursive method named to_plain_list that takes no parameters (unless they have default arguments) and returns a regular Python list that has the same values (from the data attribute of the Node objects), in the same order, as the current state of the linked list. The head data member of the LinkedList class must be private and have a get method defined (named get_head). It should return the first Node in the list (not the value inside it). As in the iterative LinkedList in the exploration, the data members of the Node class don't have to be private. The reason for that is because Node is a trivial class…

- 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:Computer Science PLEASE HELP TO CONVERT THIS FOR LOOP TO FOREACH LOOP using System;using System.Collections.Generic; namespace SwinAdventure{public class IdentifierableObject{//field ,datapublic List<string> Identifier = new List<string>(); //constructorpublic IdentifierableObject(string[] ident){for (int i = 0; i < ident.Length; i++){Identifier.Add(ident[i]);}} // Methodpublic void AddIdentifier(string id){Identifier.Add(id.ToLower());} // propertiespublic string FirstID{get{return Identifier[0];}} public bool AreYou(string id){for (int i = 0; i < Identifier.Count; i++){if (Identifier[i] == id.ToLower()){return true;} }return false;}}}Given main() and an IntNode class, complete the IntList class (a linked list of IntNodes) by writing the insertInDescendingOrder() method to insert new IntNodes into the IntList in descending order. Ex. If the input is: 3 4 2 5 1 6 7 9 8 -1 the output is: 9 8 7 6 5 4 3 2 1 import java.util.Scanner; public class SortedList { public static void main (String[] args) {Scanner scnr = new Scanner(System.in);IntList intList = new IntList();IntNode curNode;int num; num = scnr.nextInt(); while (num != -1) {// Insert into linked list in descending order curNode = new IntNode(num);intList.insertInDescendingOrder(curNode);num = scnr.nextInt();}intList.printIntList();}}

If the first element of the list is equal to the last element of the list, then the method deletes the first node. If the first element of the list is equal to the second element of the list, then the method deletes the first node. If the first element of the list is equal to the last element of the list, then the method deletes the last node.Given main() and an IntNode class, complete the IntList class (a linked list of IntNodes) by writing the insertInAscendingOrder() method that inserts a new IntNode into the IntList in ascending order.
