- Get ereor. Given a Singly Linked List of integers, delete all the alternate nodes in the list.Example:List: 10 -> 20 -> 30 -> 40 -> 50 -> 60 -> nullAlternate nodes will be: 20, 40, and 60. Hence after deleting, the list will be:Output: 10 -> 30 -> 50 -> nullNote :The head of the list will remain the same. Don't need to print or return anything.Input format :The first and the only line of input will contain the elements of the Singly Linked List separated by a single space and terminated by -1.Output Format :The only line of output will contain the updated list elements.Input Constraints:1 <= N <= 10 ^ 6.Where N is the size of the Singly Linked List Time Limit: 1 secSample Input 1:1 2 3 4 5 -1Sample Output 1:1 3 5Explanation of Sample Input 1:2, 4 are alternate nodes so we need to delete them Sample Input 2:10 20 30 40 50 60 70 -1Sample Output 2:10 30 50 70.Write an algorithm to remove 5 from the following single circular linked list? 5->4->8->9->3->headImplement 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
- 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 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…Add more methods to the singly linked list class then test them• search(e) // Return one node with 3 values (stuID, stuName, stuScore) which matches agiven key e (studentID).• addAfter(e, stuID, stuName, stuScore) //Add a new node with 3 values (stuID,stuName, stuScore) after the node with the key e (studentID).• removeAt(e) //Remove a node which matches a given key e (studentID)• count() //Return a number of nodes of list.• update(stuID, stuName, stuScore) //Update the values of one node three codes below two in pictures one,typed out. public class SlinkedList<A,B,C> { private Node head; private Node tail; private int size; public SlinkedList(){ head=null; tail=null; size=0; } public int getSize(){ return size; } public boolean isEmpty(){ return size == 0; } public A getFirstStuId(){ if(isEmpty()) return null; return (A) head.getStuID();}public B getFirstStuName(){ if(isEmpty())…

- 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…True or false: O(log n) is the worst-case run-time complexity of inserting a node into an AVL tree. True FalseFor a Doubly Linked List implement the following method: void deleteAfterHead() //Delete the second node from the list. If the list has only one element, delete the head. Assume you have deleteFromHead() and deleteFromTail() methods.
