Question 2 Which of the following statements about the code above are true? Select all that apply. You can assume that the Node class is the same one used in the HW05 JAR file. In fact, you can compile and run this code to check your answers as long as you add the JAR file to the classpath. The line marked output 3 will print null when the code is executed. OThe line marked output 4 will print simon when the code is executed. O The line marked output. 1 will print null when the code is executed. O The line marked Output 2 will print Sally when the code is executed.

there is a problem with this code  I want to delete node 10 and display the linked list after that  it cannot be displayed and I don't know why  please don't change the type of node from class to struct  the code :    #include <iostream>using namespace std; class node{public:    int data;    node* next;}; void display(node * head) // printing the data of the nodes{    node* temp = head;     while (temp != NULL) {        cout << temp->data << endl;        temp = temp->next;    }} // add                                                void push(node** head, int newdata)                    // { 5, 10 , 20 , 30 , 40 }{    node* newnode = new node();    newnode->data = newdata;    newnode->next = *head;    *head = newnode;} void append(node** head, int newdata)                // { 10 , 20 , 30 , 40 }{    node* newnode = new node();    newnode->data = newdata;    newnode->next = NULL;     node* last = *head;     if (*head == NULL) {        *head = newnode;…

You are going to implement a program that creates an unsorted list by using a linked list implemented by yourself. NOT allowed to use LinkedList class or any other classes that offers list functions. It is REQUIRED to use an ItemType class and a NodeType struct to solve this homework.  The “data.txt” file has three lines of data  100, 110, 120, 130, 140, 150, 160  100, 130, 160  1@0, 2@3, 3@END  You need to   1. create an empty unsorted list  2. add the numbers from the first line to list using putItem() function.   Then print all the current keys to command line in one line using printAll().  3. delete the numbers given by the second line in the list by using deleteItem() function.  Then print all the current keys to command line in one line using printAll()..   4. putItem () the numbers in the third line of the data file to the corresponding location in  the list. For example, 1@0 means adding number 1 at position 0 of the list.  Then print all the current keys to command line in one…

Hello all! need some help with this assignment. Need the sample output as listed in the image. Thank you!

What are the fundamental operations of a linked list and the main advantage of a linked list over an array? Test program LinkedList.java, and make sure that you understand each operation in the program. (refer to linkedListApplication.java). In this code which part I will keep main.java file and which part I will keep LinkedList.java.java file. Because I will use main.java IDE. Otherwise my program doesn't run. import java.util.*; public class LinkedList{    public Node header;     public LinkedList()    {        header = null;    }     public final Node Search(int key)    {        Node current = header;        while (current != null && current.item != key)        {            current = current.link;        }        return current;    }     public final void Append(int newItem)    {        Node newNode = new Node(newItem);        newNode.link = header;        header = newNode;    }     public final Node Remove()    {        Node x = header;        if (header != null)        {…

I have been posting the same questions but they always come with the same answer that does not use the starting code given below. Please make sure to use the following code as a starting point.  Also, please make sure to use the same class name so that I don't get confused. Please use the information in the screenshot to create a class called BST. The base of the code is given below.  Base of class Node public class Node {int key;Node left, right, parent; public Node() {} public Node(int num) {key = num;left = null;right = null;parent = null;}} Base of class BST import java.util.*; class BST {// do not change thisprivate Node root;private ArrayList<Integer> data; // DO NOT MODIFY THIS METHODpublic BST() {root = null;data = new ArrayList<Integer>(0);} // DO NOT MODIFY THIS METHODpublic ArrayList<Integer> getData() {return data;} // DO NOT MODIFY THIS METHODpublic void inOrderTraversal() {inOrderTraversal(root);} // DO NOT MODIFY THIS METHODprivate void…

Hello, I request for help with the attached problems. Thanks a lot !

Hello I need help creating " A TO DO LIST" code in java for an interactive test driver .  Your interactive test driver loop will allow users to: Add a task.  This will require you to capture the subject, priority, and dueDate.  Here are some tips on using Java LocalDates.  Use now() for the startDate.  TaskId should start at 1 and increment each time a task is added.  View the next task in the queue using the peek() method and then optionally complete the current task using the poll() method.  View a list of all tasks.   This will require the use of an iterator and the peek() method on each element.  Use isEmpty() to check if there are items in your queue and if not,  display "No tasks in queue."  View a single task by id.  This will require iterating the task list until the id is found and then displaying it.  Remove a task by id.    This will require you to iterate through the Task queue until you find the task with the matching id.  Use remove(task) and confirm to the user that the…
