- JAVA CODE Learning Objectives: Detailed understanding of the linked list and its implementation. Practice with inorder sorting. Practice with use of Java exceptions. Practice use of generics. You have been provided with java code for SomeList<T> class. This code is for a general linked list implementation where the elements are not ordered. For this assignment you will modify the code provided to create a SortedList<T> class that will maintain elements in a linked list in ascending order and allow the removal of objects from both the front and back. You will be required to add methods for inserting an object in order (InsertInorder) and removing an object from the front or back. You will write a test program, ListTest, that inserts 25 random integers, between 0 and 100, into the linked list resulting in an in-order list. Your code to remove an object must include the exception NoSuchElementException. Demonstrate your code by displaying the ordered linked list and…Course: Data Structure and Algorithms Language: C++ Question is well explained Question #2Implement a class for Circular Doubly Linked List (with a dummy header node) which stores integers in unsorted order. Your class definitions should look like as shown below: class CDLinkedList;class DNode {friend class CDLinkedList;private int data;private DNode next;private DNode prev;};class CDLinkedList {private:DNode head; // Dummy header nodepublic CDLinkedList(); // Default constructorpublic bool insert (int val); public bool removeSecondLastValue (); public void findMiddleValue(); public void display(); };Tour.java Create a Tour data type that represents the sequence of points visited in a TSP tour. Represent the tour as a circular linked list of nodes, one for each point in the tour. Each Node contains two references: one to the associated Point and the other to the next Node in the tour. Each constructor must take constant time. All instance methods must take time linear (or better) in the number of points currently in the tour. To represent a node, within Tour.java, define a nested class Node: private class Node { private Point p; private Node next; } Your Tour data type must implement the following API. You must not add public methods to the API; however, you may add private instance variables or methods (which are only accessible in the class in which they are declared). public class Tour // Creates an empty tour. public Tour() // Creates the 4-point tour a→b→c→d→a (for debugging). public Tour(Point a, Point b, Point c, Point d) // Returns the number of points in this tour. public…
- java program: University of Bahrain College of Information Technology Department of Computer Science Second Semester, 2020-2021 ITCS214 / ITCS215 / ITCS216 (Data Structures) Assignment 3 Implement generic class ArrayStack as discussed in the lectures having following methods: constructor, push, pop, peek, isEmpty, copy constructor, reallocate (private method). Also add following methods to this class: size: returns number of elements in the stack. contains: Search an element in the stack. If found returns true, else returns false. clear: Deletes all elements of the stack and make it empty stack. Implement generic class ArrayQueue as discussed in the lectures having following methods: constructor, copy constructor, offer, poll, peek, isEmpty, reallocate(private), iterator. Inner class Iter that implements interface Iterator having methods: constructor, hasNext, next. Also add following methods to the ArrayQueue class: size: returns number of elements in the queue. contains: Search…Question 20 A list is a collection with additional index- and iteration- related operations. True False Question 21 O(N) is the order of growth execution time of the size operation when using the SortedArrayCollection class, assuming a collection size of N. True False Question 22 If N represents the number of elements in the list, then the index-based set method of the ABList class is O(1). True False Question 23 O(N) is the order of growth execution time of the remove operation when using the LinkedCollection class, assuming a collection size of N. True False Question 24 It is not possible to use an array to implement a linked list. True False Question 25 O(N) is the order of growth execution time of the remove operation when using the ArrayCollection class, assuming a collection size of N. True False Question 26 Our linked implementation of lists implements a bounded list. True False Question 27 O(N) is the order of growth execution time of the contains operation…For this assignment, you need to implement link-based List and derivative ADTs in Java. To complete this, you will need the following: 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 the…
- 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: The currentSize is 3 meaning there…1. A polynomial can be represented as a linked list, where each node called a polyNode contains the coefficient and the exponent of a term of the polynomial. For example, the polynomial 4x³ + 3x² - 5 would be represented as the linked list: 43 3 4x3 I 2 % 3x² Write a Polynomial class that has methods for creating a polynomial, reading and writing a polynomial, and adding a pair of polymomials. -50 -5x° In order to add 2 polynomials, traverse both lists. If a particular exponent value is present in either one, it should also be present in the resulting polynomial unless its coefficient is zero.Write java code for a member function insertSorted(int d) for a linked list. The function traverses the list until it finds the correct location, then it inserts a node in that location. You may use the function given the class.
- Unordered Sets |As explained in this chapter, a set is a collection of distinct elements of the same type. Design the class unorderedSetType, derived from the class unorderedArrayListType, to manipulate sets. Note that you need to redefine only the functions insertAt, insertEnd, and replaceAt. If the item to be inserted is already in the list, the functions insertAt and insertEnd output an appropriate message, such as 13 is already in the set. Similarly, if the item to be replaced is already in the list, the function replaceAt outputs an appropriate message. Also, write a program to test your class.Create an implementation of a doubly linked DoubleOrderedList class. You will need to create a DoubleNode class, a DoubleList class, and a DoubleIterator classReference-based Linked Lists: Select all of the following statements that are true. As a singly linked list's node references both its predecessor and its successor, it is easily possible to traverse such a list in both directions. According to the terminology introduced in class, the head reference variable in a singly linked list object references the list's first node. According to the terminology introduced in class, in a doubly linked list, each node references both the head and tail node. In a double-ended singly linked list, the tail reference variable provides access to the entire list. In a circular linked list, the last node references the first node.
