- ANSWER THE FOLLOWING QUESTIONin python Provide python code and screenshotCourse: 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(); };
- Computer science helpWrite an abstract data type for queues whose elements store 10-characternames. The queue elements must be dynamically allocated from theheap. Queue operations are enqueue, dequeue, and empty. Use eitherC++, Java, C#, or RubyStackQueuePostfix A. Pointer_based queuea. Define the class PoiQueue with no implementation; i.e. declare the datamembers, and the function members only (Enqueue, Dequeue, IsEmpty,GetHead etc.).b. Implement the Enqueue method of the above classB. Array_based non-circular queue:a. Define the class Queue using one dimensional array representation with noimplementation; i.e. declare the data members, and the function membersonly (Enqueue, Dequeue, IsEmpty, GetHead etc.).b. Implement the Denqueue method of the above class
- Computer scienceGoal: develop a class Queue, an ordered collection of objects that restricts insertions to the rear of the queue and removal from the front of the queue •The class Queue should support methods: • ● Queue (): Constructor that initializes the queue to an empty queue enqueue (item): Add item to the end of the queue dequeue (): Remove and return the element at the front of the queue isEmpty(): Returns True if the queue is empty, False otherwise appts Queue () >>> appts.enqueue ('John') >>> appts.enqueue ('Annie') >>> appts.enqueue ('Sandy') >>> appts.dequeue () 'John' >>> appts.dequeue () 'Annie' >>> appts.dequeue () 'Sandy' >>> appts.isEmpty() TrueWrite an abstract data type for a queue whose elements include both a 20-character string and an integer priority. This queue must have the following methods: enqueue, which takes a string and an integer as parameters; dequeue, which returns the string from the queue that has the highest priority; and empty. The queue is not to be maintained in priority order of its elements, so the dequeue operation must always search the whole queue.
- 2. Given the abstract data type (ADT) for static queue template in Queue.h below template class Queue { private: T *queueArray; int queueSize; int front; int rear; int numItems; public: Queue (int); Queue (const Queue &); -Queue (); void enqueue (T); void dequeue (T &); void splitqueue (T &); bool isEmpty() const; bool isFull() const; void clear (); } ; (a) Write the full definition for the public member method splitqueue that splits the contents of a queue into two different queues i.e. Odd_queue and Even_queue. This method print the appropriate queue based on user choice of 1 and 2 where 1 is for Odd queue and 2 for Even queue.Goal: develop a class Queue, an ordered collection of objects that restricts insertions to the rear of the queue and removal from the front of the queue •The class Queue should support methods: • .
