Implement a Single linked list to store a set of Integer numbers (no duplicate)
• Instance variable
• Constructor
• Accessor and Update methods
2.) Define SLinkedList Class
a. Instance Variables:
# Node head
# Node tail
# int size
b. Constructor
c. Methods
# int getSize() //Return the number of nodes of the list.
# boolean isEmpty() //Return true if the list is empty, and false otherwise.
# int getFirst() //Return the value of the first node of the list.
# int getLast()/ /Return the value of the Last node of the list.
# Node getHead()/ /Return the head
# setHead(Node h)//Set the head
# Node getTail()/ /Return the tail
# setTail(Node t)//Set the tail
# addFirst(E e) //add a new element to the front of the list
# addLast(E e) // add new element to the end of the list
# E removeFirst()//Return the value of the first node of the list
# display()/ /print out values of all the nodes of the list
# Node search(E key)//check if a given k is in the list, return found nodes or null
# Node update(E key, E e)//update the value of a given k to new value, return updated node

- In java The following is a class definition of a linked list Node:class Node{int info;Node next;}Assume that head references a linked list and stores in order, the int values 5, 7 and 9. Show the instructions needed to delete the Node with 5 so that head would reference the list 7 and 9.arrow_forwardSorting Create a MyLinkedList class with inner Node class, data fields, and the insert(element) method. Implement a toString method to return all nodes in MyLinkedList. Implement a recursive sorting and a non-recursive sorting method.arrow_forwardGiven 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 }arrow_forward
