Solved in 2 steps
- ALL TRUE OR FALSE QUESTIONS 1. A "deque" allows an application to enqueue and dequeue from both front and rear of a queue. 2. The Queue ADT of the text is defined to hold elements of type Objec 3. Java supports inheritance of interfaces. 4. The text's array-based queue implementations use the fixed-front approach. 5. If N represents the number of elements in the queue, then the dequeue method of the ArrayBoundedQueue class is O(1). 6. When an object of class LinkedQueue represents an empty queue, its rear variable is 0. 7. A standard linked list provides a good implementation of a "Deque". 8. When implementing a queue with a linked list, the front of the queue is also the front of the linked list. 9. Our LinkedQueue class implements the QueueInterface interface. 10. The text's array-based queue implementations use the floating-front approach.The Deque ADT combines characteristics of the Stack and the Queue. The name “Deque" comes from "double-ended queue" and is usually pronounced "deck". Like the Stack and the Queue, a Deque permits elements to be accessed only at the ends. However, a Deque allows items to be added at either end and removed from either end. We can refer to the operations supported by the Deque as enqueueFront, enqueueRear, dequeueFront, and dequeueRear. Note that once you have a Deque, you can use it to implement both the Stack and the Queue. Implement the Deque using a dynamic, linked implementation (15pts) Use your Deque to implement a Stack (15pts). Use your Deque to implement a Queue (15pts). Test your implementation across the 3 data structures to tell the story of your work (10pts).Problem Description: 1. Suppose that we want to add a method to a class of queues that will splice two queues together. This method adds to the end of a queue all items that are in a second queue. The header of the method could be as follows: public void splice (QueueInterface anotherQueue) Write this method in such a way that it will work in any class that implements QueueInterface.
- Assignment 05 PART 1 Queues - Note Part 1 is a separate deliverable: Write a class with a main method that uses a priority queue to store a list of prioritized chores. This is all the information that is provided. The rest is up to you. You may decide how to store your chores and how to store your priorities. YOU MUST WRITE your own Queue class – do not use the Java Library, Queue Class.A double-ended queue or deque is a generalization of a stack and a queue that supports adding and removing items from either the front or the back of the data structure. This assignment has two parts: Part-1 Create a doubly linked list based DeQueDLL class that implements the DequeInterface. The class skeleton and interface are provided to you. Implement a String toString () method that creates and returns a string that correctly represents the current deque. Such a method could prove useful for testing and debugging the class and for testing and debugging applications that use the class. Assume each queued element already provides its own reasonable toString method. Part-2 Create an application program that gives a user the following three options to choose from – insert, delete, and quit. If the user selects ‘insert’, the program should accept the integer input from the user and insert it into the deque in a sorted manner. If the user selects ‘delete’, the program should…1 Implement a Queue Data Structure specifically to store integer data using a Singly Linked List. 2 The data members should be private. 3 You need to implement the following public functions: 4 1. Constructor: 5 It initialises the data members as required. 6 7 8 2. enqueue(data) : This function should take one argument of type integer. It enqueues the element into the queue and returns nothing. 3. dequeue(): It dequeues/removes the element from the front of the queue and in turn, returns the element being dequeued or removed. In case the queue is empty, it r 4. front (): 10 11 It returns the element being kept at the front of the queue. In case the queue is empty, it returns -1. 12 5. getSize(): 13 It returns the size of the queue at any given instance of time. 14 6. 1sEmpty(): 15 It returns a boolean value indicating whether the queue is empty or not. 16 Operations Performed on the Stack: 17 Query-1 (Denoted by an integer 1): Enqueues an integer data to the queue. 18 19 Query-2…
- If the elements “A”, “B”, “C” and “D” are placed in a queue and are removed one at a time, in what order will they be removed?1. Assume you have a queue with operations: enqueue(), dequeue(), isEmpty(). How would you use the queue methods to simulate a stack, in particular, push() and pop() ? Hint: use two queues, one of which is the main one and one is temporary.Student should be able to develop the programs for queue using arrays and linked list By Using C++ software. Exercise 1: Implementation of Queue using Array or Linked list Consider a real life situation. Formulate a question and then design a simulation that can help to answer it. Choose one of the following situations: • Cars lined up at a car wash • Customers at a grocery store check-out • Airplanes taking off and landing on a runway • A bank teller Be sure to state any assumptions that you make and provide any probabilistic data that must be considered as part of the scenario.
- Assume the Queue is initially empty. class Queue { public: int size () ; bool empty (); chará front () throw (Exception); void enqueue (char& e); void dequeue () throw (Exception); Function call Output Queue Contents (back -> front) enqueue ('A') enqueue ('B') front ( ) size ( ) dequeue () enqueue ('C') empty( ) dequeue ( ) size( ) dequeue () empty ( ) front ( ) enqueue ('D') front () dequeue () dequeue ( )In java The following is a class definition of a linked list Node:class Node{int info;Node next;}Assume that head references a linked list and stores in order, the int values 5, 7 and 9. Show the instructions needed to delete the Node with 5 so that head would reference the list 7 and 9.====================================== Answer question below: - Write Java code. Implement a MyQueue class which implements a queue using two stacks. private int maxCapacity = 4; private Stack<String> stack1; private Stack<String> stack2; Note: You can use library Stack but you are not allowed to use library Queue and any of its methods Your Queue should not accept null or empty String or space as an input You need to implement the following methods using two stacks (stack1 & stack2) and also you can add more methods as well: public int size() public void insert(String value) public String remove() private void shiftStacks() public boolean isEmpty() public boolean isFull() Test case1: Testing empty queue - Input1: 1 - Output1: [0:Empty:] Test case2: Testing insert method - Input2: 2 4 a b c d - Output2: [4:Full:a, b, c, d] Test case3: Testing remove method - Input3: 3 4 a b c d - Output3: [3:b, c, d] *MyQueue.java: import java.util.*; import java.lang.*; import…
