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…

Don't copy from other websties a) Write a function to get the value of the Nthnode in a Linked List. [Note: The first (N=1) item in the list means the item at index 0.] It takes two parameters: the list or its head, and N. Return False if the list has fewer than N elements. The Linked List structure supports the following function. def getHead(self): return self.head # it points to a Node structure The Node structure supports the following functions. def getData(self): return self.data # it returns the value stored in the Node def getNext(self): return self.next # it points to the next Node b) Write a function that counts the number of times a given integer occurs in a Linked List. Assume similar structures as defined in 1.

Consider the following linked list of the form. This list already exists, so you do not need to write the code to create the list below: struct nodeType { int infoData; nodeType * next; }; nodeType *first; … and containing the values: first (( See image for values )) Use this linked list to perform the following actions. Declare any additional pointers, etc., if needed, to complete the code. You do not need to write any includes or using statements—just program segments. Write a code segment that creates a new node with infoData = 13 and inserts the node after the node with the value 12.
write a program for a library automation which gets the isbn number, name, author and publication year of the books in the library. the status will be filled by the program as follows: if publication year before 1985 the status is reference else status is available, the information about the books should be stored inside a linked list. the program should have a menu and the user inserts, displays, and deletes the elements from the menu by write a selecting options. the following data structure should be used. struct list char isbn[ 20 ]: char namei 20 ]. char authori 20 ]: int year; char status[200j: struct list "next, jinfo, wedoad n un posn ag pinogs nuu sulnogoj l press 1. to insert a book press 2. to display the book list press 3. to delete a book from list

Java Please provide Comment and test cases. PLease see attachment Create a Linked List data structure by writing your own Linked List class which contains a node class. The node class will house the data (integer in this case) and a pointer to the next node element. Populate your linked list with the following integers and print it . 50, 11, 33, 21, 40, 71 No you do not need to print the commas ;) Delete N-th node from the end of the linked list and print the linked list after deletion. Here N = 2 Below is the expected output after deleting the second last element. 50, 11, 33, 21, 71 ATTN : Note : Here we do not know the length of the list. Complete the above deletion operation without calculating the length of the list. Your solution should only make a single pass through the linked list, adhering to O(n) time complexity overall and O(1) space complexity. Hint : Maintain two pointers : a ’Fast’ Pointer and a ’Slow’ pointer. Initialize both pointers to a dummy node which points to…
struct nodeType { int infoData; nodeType * next; }; nodeType *first; … and containing the values(see image) Using a loop to reach the end of the list, write a code segment that deletes all the nodes in the list. Ensure the code performs all memory ‘cleanup’ functions.
