6. Suppose that we have defined a singly linked list class that contains a list of unique integers in ascending order. Create a method that merges the integers into a new list. Note the additional requirements listed below. Notes: . . Neither this list nor other list should change. The input lists will contain id's in sorted order. However, they may contain duplicate values. For example, other list might contain id's <2,3,3,5,5,5,6>. You should not create duplicate id's in the list. Important: this list may contain duplicate id's, and other list may also contain duplicate id's. You must ensure that the resulting list does not contain duplicates, even if the input lists do contain duplicates.

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…

java program java method: Write a method replace to be included in the class KWLinkedList (for doubly linked list) that accepts two parameters, searchItem and repItem of type E. The method searches for searchItem in the doubly linked list, if found then replace it with repItem and return true. If the searchItem is not found in the doubly linked list, then insert repItem at the end of the linked list and return false. Assume that the list is not empty. You can use ListIterator and its methods to search the searchItem in the list and replace it with repItem if found. Do not call any method of class KWLinkedList to add a new node at the end of the list. Method Heading: public boolean replace(E searchItem, E repItem) Example: searchItem: 15 repItem: 17 List (before method call): 9 10 15 20 4 5 6 List (after method call) : 9 10 17 20 4 5 6
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.
1- Start by writing your choice from the list given above. Part a. Explain the important technical details about your choice. 2-(continued) Start by again writing your choice from the list given above. Part b. Most of the ADTs in this class were implemented using arrays and linked lists. If appropriate for the ADT you chose in part a., explain which one (an array or a linked list) you would choose to implement it and why. If it doesn’t make sense to implement your ADT using an array or a linked list, explain which other data structure you would use to implement your ADT.
Assume that the linked list class is ready and called (MyLinkedList) that contains nodes with int data, and next reference. Assume also that MyLinkedList contains only the following methods: addFirst(), addLast(), removeFirst(), removeLast(). Given that numbers are represented in linked lists (i.e. the number 567 will be represented in a linked list of three nodes; the first node contains 5, the second node contains 6 and the last node contains 7. Write a java method that receives the heads of two linked lists representing two numbers and finds the product (result of multiplication) list and returns its head. Note: You are free to use only one additional stack in your solution.
1. Consider an ADT list of integers. Write a method that computes the maximum of the integers in the list aList. The definition of your method should be indepen- dent of the list's implementation.
Need help only part 2. Thank you! In this assignment, you will create a Linked List data structure variant called a “Circular Linked List”. The Node structure is the same as discussed in the slides and defined as follows (we will use integers for data elements): public class Node { public int data; public Node next; } For the Circular Linked List, its class definition is as follows: public class CircularLinkedList { public int currentSize; public Node current; } In this Circular Linked List (CLL), each node has a reference to an existing next node. When Node elements are added to the CLL, the structure looks like a standard linked list with the last node’s next pointer always pointing to the first. In this way, there is no Node with a “next” pointer in the CLL that is ever pointing to null. For example, if a CLL has elements “5”, “3” and “4” and “current” is pointing to “3”, the CLL should look like: Key observations with this structure:…
Exercise 1• Create a class that sorts a list in ascending order. Make use of the Collections method sort• The list should be a list of Strings.• Test your code with {“Hearts”, “Diamonds”, “Clubs”, “Spades”}• Before and after the sort, use the implicit call to the list’s toString method to output the list contents. Exercise 2• Create a class with the same requirement as in Exercise 1, but the sort should be in descending order• Make use of the Comparator interface• Make use of the static collection method reverseOrder java
Write a Python code using the given function and conditions. Do not use Numpy. Use LinkedList Manipulation. Given function: def insert(self, newElement, index) Pre-condition: The list is not empty. Post-condition: This method inserts newElement at the given index of the list. If an element with the same key as newElement value already exists in the list, then it concludes the key already exists and does not insert the key. [You must also check the validity of the index].
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…
