- A data structure called a deque is closely related to a queue. The name deque stands for “double-ended queue.” The difference between the two is that with a deque, you can insert, remove, or view from either end of the queue. Implement a deque using arraysA deque data structure and a queue are related ideas. The abbreviation "deque" stands for "double-ended queue." A deque differs from the other two in that you may insert, remove, or view from either end of the queue. Implement a deque using arrays.A queue and a deque data structure are related concepts. Deque is an acronym meaning "double-ended queue." With a deque, you may insert, remove, or view from either end of the queue, which distinguishes it from the other two.

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.Exercise 1: Implementation of Queue using Array or Linked list Consider a real life situation.

- Queue Simulation Create a java program that will simulate Queue operations using 1-D array representation.Each operation is dependent from each other and it's carried out in the next question in a sequential order. Given: A Queue with 10 elements.Following initial state of a queue is reflecting the implementation of a circular array. The front and back pointers are shown on the queue. 67 32 45 b. enqueue(95) c. dequeue front Show the queue state after each of the following operations with updating front and back pointers as required: a. enqueue(23) d. dequeue e. enqueue(11) f. dequeue g. dequeue h. dequeue 44 backIf the following is a circular array based queue of size 99 43 54 76 93 77 18 If rear is at index 1 and front is at index 6, what is the size of the queue?
- in the array based queue, if the rear = front then Select one: a. the queue is empty b. the queue must have many items C. the queue is full d. the queue has one itemThe implementation of a queue in an array, as given in this chapter, uses the variable count to determine whether the queue is empty or full. You can also use the variable count to return the number of elements in the queue. On the other hand, class linkedQueueType does not use such a variable to keep track of the number of elements in the queue. Redefine the class linkedQueueType by adding the variable count to keep track of the number of elements in the queue. Modify the definitions of the functions addQueue and deleteQueue as necessary. Add the function queueCount to return the number of elements in the queue. Also, write a program to test various operations of the class you defined.In C++, develop an algorithm that adds the value val to a queue object Q. The queue is represented using an array data of size s. The algorithm should assume that the queue is not full. The most recently added item is at index r (rear), and the least recently added item is at index f (front). If the queue is empty, r = f = -1.
