Lab 20 Removing the first element in a list Start this lab with the code listed below. The LinkedList class defines the rudiments of the code needed to build a linked list of Nodes. Complete the code for the removeFirst method, which should remove and return the first element in the linked list. Throw a NoSuchElementException if the method is invoked on an empty list. Use the LinkedListRunner class's main method to test your code. import java.util.NoSuchElementException; public class LinkedList private Node first; public LinkedList () { first = null; } public Object getFirst () if (first == null) { throw new NoSuchElementException (); }

Finding the first and last occurrence of a value (doubly-linked list) Given main.py and a PersonNode class, complete the PersonList class by writing find_first() and find_last() methods at the end of the PersonList.py file. The find_first() method should find the first occurrence of an age value in the linked list and return the corresponding node. Similarly, the find_last() method should find the last occurrence of the age value in the linked list and return the corresponding node. For both methods, if the age value is not found, None should be returned. The program will replace the name value of each found node with a new name. Ex. If the input is: Alex 23 Tom 41 Michelle 34 Vicky 23 -1 23 Connor 34 Michela the output is: List before replacing: Alex, 23 Tom, 41 Michelle, 34 Vicky, 23 List after replacing the first occurrence of 23: Connor, 23 Tom, 41 Michelle, 34 Vicky, 23 List after replacing the last occurrence of 34: Connor, 23 Tom, 41 Michela, 34 Vicky, 23 PYTHON PLZ
Question 2: Using only LLNode java cass. Create a demo cass called LinkedlistDemo java. In this demo class, write a public static method called SumNode that receives a reference caled list of type LLNode of integer values. Your method shoukl sum all the nodes content and then add a new node contains the summation to the end of the list. For example, if the list contains: list Then after calling the method SumNode, the list becomes: list 36 11------- Paste SumNode code below this line Good Luck O
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:
In Java, Create Movie class, which has private fields for title, director, rating. It has a constructor to initialize these fields and a toString method for printing movie details. There is also a getRating method to retrieve the movie rating. Create Rating Comparator class which implements the Comparator interface for comparing movies based on their ratings. Create DemoMovies Class. Initialize necessary data structures like LinkedList, TreeMap for rating as key and Movie from Movie class as value, TreeSet, and ProtiyQueue. Use a loop to take user input for movie detailsuntil the user enters 'WWW' as the movie title.Inside the loop, for each movie, create a Movie object, add it to various data structures that is title, director and rating based on the constructor. Add the Movie object to the LinkedList. Add the rating and the object to the TreeMap.Add the rating to the TreeSet.Add the Movie object to the Priority Queue.Display the entered movies. Sort and display Movies by rate by…

Given the source code of linked List, answer the below questions(image): A. Fill out the method printList that print all the values of the linkedList: Draw the linked list. public void printList() { } // End of print method B. Write the lines to insert 10 at the end of the linked list. You must draw the final linked List. Notice that you can’t use second or third nodes. Feel free to define a new node. Assume you have only a head node C. Write the lines to delete node 2. You must draw the final linked list. Notice that you can’t use second or third node. Feel free to define a new node. Assume you have only a head node

Assume you have a method (shown below) inside the single linked list class, what does this method do? private E remove () { Node temp = head; if (head != nulI) { head = head.next; size--; return temp.data } else return null; } (A Remove the first node in the list and return the data of the deleted node or null if the list is empty. Remove the node after the node referenced by temp and return the data of the deleted node or null if the list is (в empty. Remove all the nodes of the linked list and return the data of the last node deleted or null if the list is empty.
Problem2. Write a program that will remove an elements to an ArrayList/LinkList. Filename: ArrListRem.java
Write the following method in Java: public void reverse() The method will reverse the linked list. Head will point to the last node of the linked list and all the pointers (addresses) will be reversed. The last node (a new head) will point to the second last node and so on. The old head node will become the tail node in the reversed LinkedList. Use the LinkedList class discussed in the video lecture and write the reverse() method in the same class. Test your method in the main method. Following picture depicts the reversal of the LinkedList. NULL Head I V R I ↑ Head > NULL
