- Calculate the performance of addFirst, remove(Object), and removeLast for each of the three implementations (Vectors may be included if desired). Which implementations do the best with short lists? Which implementations are the most efficient for huge lists?Is it possible to implement a sorted linked list using a DLL? What is the advantage of using a DLL versus a single linked list? Back up your point with a real example or application.As a student who is currently doing CMPG22, you have been asked to analyse, model and design a LinkedList System that will be used to perform some manipulations on the data list by high school students and their instructors. The list will be given to the system as input and the user will perform some actions on the data as follows: 1. Return the first element in the list, 2. return the last element in the list, 3. remove the head and return the object stored in the removed node, 4. add a new element to the front of the list, 5. add a new element to the end of the list, 6. delete the first item in the list with the SAME VALUE, 7. determine whether a specific object is present (according to value), 8. receives a second linked list as a parameter and will return a third list containing all the elements of the parameter list which are not present in the calling list and lastly, 9. receive the second linked list as a parameter, and return a new linked list consisting of both the parameter…
- Implement a city database using ordered lists by using java. Each database record contains the name of the city (a string of arbitrary length) and the coordinates of the city expressed as integer x and y coordinates. Your database should allow records to be inserted, deleted by name, and searched by name. Another operation that should be supported is to print all records within a given distance of a specified point/coordinate. The order of cities should be alphabetically by city name. Implement the database using both: an arraybased list implementation, and a circular single linked list implementation.Use may the following node, SLL implementations to implement an ordered circular single linked listInstruction: 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…Given a scenario where you need to efficiently insert elements at the beginning of a list, which type of linked list would be most suitable? Explain why.
- Create an implementation of singly linked list using classes with minimum 5 nodes (spectre, togusa, yuri, siren, shepherd) in Python with the following capabilities/functions: Traverse - print out all data from the linked list Insert - generate a node and attach to an existing linked list Search - find an item (data) from the linked list and return the node Remove - remove a node from the linked listSuppose we want to extend the PositionalList ADT with a method, indexOf(p), that returns the current index of the element stored at position p. Write this method using only other methods of the PositionalList interface (not details of our LinkedPositionalList implementation). Write the necessary code to test the method. Hint: Count the steps while traversing the list until encountering position p public interface PositionalList<E> extends Iterable<E> { int size(); boolean isEmpty(); Position<E> first(); Position<E> last(); Position<E> before(Position<E> p) throws IllegalArgumentException; Position<E> after(Position<E> p) throws IllegalArgumentException; Position<E> addFirst(E e); Position<E> addLast(E e); Position<E> addBefore(Position<E> p, E e) throws IllegalArgumentException; Position<E> addAfter(Position<E> p, E e) throws IllegalArgumentException; E set(Position<E> p, E e) throws…There’s a somewhat imperfect analogy between a linked list and a railroad train, where individual cars represent links. Imagine how you would carry out various linked list operations, such as those implemented by the member functions insertFirst(), removeFirst(), and remove(int key) from the LinkList class in this hour. Also implement an insertAfter() function. You’ll need some sidings and switches. You can use a model train set if you have one. Otherwise, try drawing tracks on a piece of paper and using business cards for train cars.

Create a java program which contains three threads and demonstrate how they can be prioritised. c.) Given the following interfaceImplement linked based list and ADTs in Java, fullfilling all conditions listed below Remember to use the code images below for data attributes: A LinkNode structure or class which will have two attributes - a data attribute and a pointer attribute to the next node. The data attribute of the LinkNode should be the Money class of Lab 1. A Singly Linked List class which will be composed of three attributes - a count attribute, a LinkedNode pointer/reference attribute pointing to the start of the list and a LinkedNode pointer/reference attribute pointing to the end of the list. Since this is a class, make sure all these attributes are private. The attribute names for the Node and Linked List are the words in bold in #1 and #2. For the Linked List, implement the most common linked-list behaviors as explained in class - getters/setters/constructors/destructors for the attributes of the class, (a) create new list, (b) add data, (c) delete data, (d) find data, (e) count of data items in…
