- An array of size MAX_SIZE is used to implement a queue. head, tail, and size are tracked. Suppose front is 0 and rear is MAX_SIZE -1. How many elements are present in the queue? a. 0 b. MAX_SIZE-1 c. MAX_SIZE d. 1We can declare a new array and copy the items of the old queue to new and by this, it will extend the size of the queue.Suppose x is a linked-list node and not the last node on the list. What is the effect of the following code fragment?x.next = x.next.next;
- Imagine you have an empty Queue of integers, Q, with 5 elements size, and two integer numbers x and y. Draw a picture of Q, x and y after executing the following code:Suppose that x is a linked list Node. What does the following code fragment do?t.next = x.next;x.next = t;The 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 java how do you: Delete the lowest/smallest item from the Circular Linked List (provided the list is sorted in ascending order) Reverse a Stack S, using a Queue Q Add the top 2 elements of a Stack S. Return the addition and push the data back in the stack S. How to reverse a Queue using a Stack? How to reverse a Queue using an array?What's the point of constructing this cumbersome circular array stack? For some reason, a circular array is the only viable option for implementing queues.In C++, Write a program which is menudriven ( i) Enque, ii) Deque, iii) Peek iv) Print). It will create a circularQueue of integer type data using array. You have to implement the followingoperations.a. Enqueue (Insert a data to the queue)b. Dequeue (Remove an item from the queue and printit)c. Peek (Print the item at the Front)Print (Print the elements present at the queue)
- Create a queue with three stacks, so that each queue operation requires a fixed (worst-case) number of stack operations. Caution: this game is quite challenging.What is the main advantage of implementing a queue using a linked list rather than an array?Write a Java program that allow the user 1.Implement a queue in an array2. Enter the following number 3,4,6,7,2,1,0) in the queue 3. Reverse the queue element using a stack to display them in this order (i.e. 0,1,2,7,6,4,3).
