C++ ProgrammingActivity: Deque Linked List Explain the flow of the code not necessarily every line, as long as you explain what the important parts of the code do. The code is already correct, just explain the flow. #include "deque.h" #include "linkedlist.h" #include <iostream> using namespace std; class DLLDeque : public Deque { DoublyLinkedList* list; public: DLLDeque() { list = new DoublyLinkedList(); } void addFirst(int e) { list->addAt(e,1); } void addLast(int e) { list->addAt(e,size()+1); } int removeFirst() { return list->removeAt(1); } int removeLast() { return list->removeAt(size()); } int size(){ return list->size(); } bool isEmpty() { return list->isEmpty(); } // OPTIONAL: a helper method to help you debug void print() {…

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(); };
JAVA programming language DescriptionYour job is to write your own array list (growable array) that stores elements that are objects of a parentclass or any of its child classes but does not allow any other type of objects to be stored. You will createa general data class and two specific data classes that inherit from that class. You will then write thearray list to hold any objects of the general data class. Finally, you will test your array list using JUnittests to prove that it does what it should.DetailsYour array list must be named DataList. Start with an array with room for 10 elements. Keep all elementscontiguous (no blank places) at the low end of the indices. When the array is full, grow it by doubling thesize. (Do not use any built-in methods to copy the array elements. Write your own code to do this.) Youdo not have to shrink the array when elements are removed. The array list must have the followingpublic methods (listed in UML style where GenClass is your general data…
Assume a Node class has been defined using the Node class implementation in your textbook, except that the data members have been declared public instead of private. This means that the code shown below has direct access to the data members defined inside the Node class. Type the EXACT output of the following code segment. You may assume that the code compiles and executes without errors. Nodecchar> "ptr1; Nodecchar> "ptr2; Node *top; char ch; - new Nodecchar>; top - ptr1; ptr1->item - 'S': ptr1 ptr1 - new Nodecchar>; top->next - ptr1; ptr1->item - 'R'; for (ch - 'E'; ch >- A; ch-) { ptr2 - new Nodecchar>; ptr1->next - ptr2; ptr2->item - ch; ptri - ptr1 -> next; ptr1->next - nullptr; ptr2 - top->next; ptr2 - ptr2->next; ptr1 - ptr2->next; ptr1 - ptr1->next; cout item item next; ptr1 - top->next; cout item item item << endl; [1]
@6 The Reference-based Linked Lists: Select all of the following statements that are true. options: 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.

Computer Science Part 2: Client Program with ArrayList Create a second client program. This program will contain an ArrayList of StudentGrades objects. The program will perform the following tasks: Create an instance of an ArrayList that will store three StudentGrades objects. Each element in the ArrayList represents student grades for a test (assessment). This means that each StudentGrades object stored by the ArrayList element represents the grades achieved by students for a single test. Prompt the user for the number of students in the class. The prompt text is: Enter the number of students in the course: [Keyboard Input] Add three new StudentGrades objects to the ArrayList. The StudentGrades objects should be populated with random values from 0 to 100. Use the enhanced for loop to print each of the StudentGrades objects to the console. Print a line containing the following text: “LAST ELEMENT BEFORE REMOVE:”. Print the value of the final element in the ArrayList under the heading.…
