Suppose we want to implement a circular queue using an array that has an initial capacity (maximum number of elements) MAX. A circular queue is like a regular queue except that elements can be enqueued or dequeued by wrapping around it. Assume we enqueue on the tail and dequeue from the head. An example circular queue with sample operations is shown below: head head tail head tail tail head Enqueue(9) a) Write a program in C that implements this circular...

Suppose we have an array-based queue (circular buffer) of size 6: int data[6]; int front = 0, back = 0; void enqueue(int x) { data[back] = x; back = (back + 1) % 6; } void dequeue() { front = (front + 1) % 6; } and we perform the following series of queue operations: enqueue(1); dequeue(); enqueue(2); dequeue(); enqueue(7); enqueue(3); enqueue(5); dequeue(); dequeue(); enqueue(4); enqueue(6); Write the state of the queue array after each operation, and at the end,...

(C++) (VISUAL STUDIO) Circular Queue is a linear data structure in which the operations are performed based on FIFO (First In First Out) principle and the last position is connected back to the first position to make a circle. In a normal Queue, we can insert elements until queue becomes full. But once queue becomes full, we cannot insert the next element even if there is a space in front of queue. Efficiently implement a queue class using a circular...

3. A queue implementation is being done using a circular array. It has a front and a rear index for the array. Given that the queue length is q.length, give the following tests: How do you test if the queue is empty? How do you test if the queue is full? Assuming the queue is not empty, how do you remove an item from the queue? (How do you update the values for front and/or rear?) Assuming the queue is...

[Java] Efficiency Comparison of two Implemented Queues : Circular Array Queue and SSQueue and its enqueue and dequeue operations Need to write a program that compares the efficiency of the queue implementations. To do so, you need to find and compare the running times of 1 the following two scenarios for both queue implementations: 3.1 Scenario 1: Alternating Sequence of Enqueues and Dequeues For every n ∈ {20, 50, 100, 1000, 10000, 100000, 1000000}, do the following: 1. long startTime...

Suppose the following operations are performed on a queue containing integers. Create an empty queue Push 1 Push 2 Push 3 Pop Push 4 Push 5 Pop Now do the following: a. Draw a sketch of a doubly linked-list based queue after steps 1-4. b. Draw a sketch of a doubly linked-list based queue after all steps 1-8. c. Draw a sketch of a circular array-based queue with capacity 6 after steps 1-4. Specify f, t, and size after each...

In this assignment you will be implementing two Abstract Data Types (ADT) the Queue ADT and the Stack ADT. In addition, you will be using two different implementations for each ADT: Array Based Linked You will also be writing a driver to test your Queue and Stack implementations and you will be measuring the run times and memory use of each test case. You will also be adding some functionality to the TestTimes class that you created for Homework 1....
