Step by step
Solved in 2 steps
- 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…please follow instructions correctly. You are required to complete the LinkedList class. This class is used as a linked list that has many methods to perform operations on the linked list. To create a linked list, create an object of this class and use the addFirst or addLast or add(must be completed) to add nodes to this linked list. Your job is to complete the empty methods. For every method you have to complete, you are provided with a header, Do not modify those headers(method name, return type or parameters). You have to complete the body of the method. package chapter02; public class LinkedList { protected LLNode list; public LinkedList() { list = null; } public void addFirst(T info) { LLNode node = new LLNode(info); node.setLink(list); list = node; } public void addLast(T info) { LLNode curr = list; LLNode newNode = new LLNode(info); if(curr == null) { list = newNode; } else…Having trouble with creating the InsertAtEnd function in the ItemNode.h file below. " // TODO: Define InsertAtEnd() function that inserts a node // to the end of the linked list" Given main(), define an InsertAtEnd() member function 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 ------------------------------------------------------- main.cpp -------------------------------------------------------- #include "ItemNode.h" int main() { ItemNode *headNode; // Create intNode objects ItemNode *currNode; ItemNode *lastNode; string item; int i; int input; // Front of nodes list headNode = new ItemNode(); lastNode = headNode; cin >> input; for (i = 0; i < input; i++) { cin >> item;…
- Implementing a Double-Ended List:contains the firstLastList.cpp program, which demonstrates a doubleended list. (Incidentally, don’t confuse the double-ended list with the doubly linked list, which we’ll explore later in Hour 10, “Specialized Lists.”)A business that sells dog food keeps information about its dog food products in a linked list. The list is named dogFoodList. (This means dogFoodList points to the first node in the list.) A node in the list contains the name of the dog food (a String), a dog food ID (also a String) and the price (a double.) a.) Create a class for a node in the list. b.) Use this class to write pseudocode or Java for a public method that prints the name of all dog foods in the list where the price is more than $20.00.You may find a doubly-linked list implementation below. Our first class is Node which we can make a new node with a given element. Its constructor also includes previous node reference prev and next node reference next. We have another class called DoublyLinkedList which has start_node attribute in its constructor as well as the methods such as: 1. insert_to_empty_list() 2. insert_to_end() 3. insert_at_index() Hints: Make a node object for the new element. Check if the index >= 0.If index is 0, make new node as head; else, make a temp node and iterate to the node previous to the index.If the previous node is not null, adjust the prev and next references. Print a message when the previous node is null. 4. delete_at_start() 5. delete_at_end() . 6. display() the task is to implement these 3 methods: insert_at_index(), delete_at_end(), display(). hint on how to start thee code # Initialize the Node class Node: def __init__(self, data): self.item = data…
- Instruction: To test the Linked List class, create a new Java class with the main method, generate Linked List using Integer and check whether all methods do what they’re supposed to do. A sample Java class with main method is provided below including output generated. If you encounter errors, note them and try to correct the codes. Post the changes in your code, if any. Additional Instruction: Linked List is a part of the Collection framework present in java.util package, however, to be able to check the complexity of Linked List operations, we can recode the data structure based on Java Documentation https://docs.oracle.com/javase/8/docs/api/java/util/LinkedList.html package com.linkedlist; public class linkedListTester { public static void main(String[] args) { ListI<Integer> list = new LinkedList<Integer>(); int n=10; for(int i=0;i<n;i++) { list.addFirst(i); } for(int…o create the linkage for the nodes of our linkedlist. The class includes several methods for adding nodes to the list, removingnodes from the list, traversing the list, and finding a node in the list. We alsoneed a constructor method that instantiates a list. The only data member inthe class is the header node.use c#A deque (pronounced “deck”) is a list-based collection that allows additions and removals to take place at both ends. A deque supports the operations addFront(x), removeFront( ), addRear(x), removeRear( ), size( ), and empty( ). Write a class that implements a deque that stores strings using a doubly linked list below. Demonstrate your class with a graphical user interface that allows users to manipulate the deque by typing appropriate commands in a JTextField component, and see the current state of the deque displayed in a JTextArea component. Consult the documentation for the JTextArea class for methods you can use to display each item in the deque on its own line. ########################################################################################################################## import java.util.Objects; public class DoublyLinkedList<E> {Node head;DoublyLinkedList() {head = new Node(null, null, null);} /** Appending the first item in the list **/public Node addFirst(E…
