Stack, Queue and Deque
5.1. Understand the basic operations for Stack, Queue and Deque
Example: Suppose that Queue q is implemented by a circular array data with the size 3. Please draw
the state of the Queue q and circular array data after each of the following steps.
1) Queue q = new Queue();
2) q.enqueue(5);
3) q.enqueue (2);
4) q.enqueue (9);

- 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 backRadix Sorting Algorithm In C++, implement the radix sorting algorithm using a queue class.Steps: Create a queue filled with 10 random integers between 1000 and 9999. Next, create a list of 10 empty queues (0-9 digit bins), then dequeue each number from the main queue and enqueue them into the correct digit bin. Dequeue the numbers from each digit bin in order and enqueue them back into the main queue. Repeat the process for every digit (tens, hundreds, thousands, etc.) Finally, print the sorted list.Your job is to implement a Stack using only a Queue(s). That is, you will be responsible for writing the push and pop methods for a Stack but your internal data representation must be a Queue: void push(Queue& queue, int element) int pop(Queue& queue)
- 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. Use arrays to implement a deque1. 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.1. What happens when the 11th item is added to a stack or queue? 2. What is the number of the next item, after the 11th, that would cause the same process you just described (in Question 1) to occur? 3. Assume you have 5 items in a stack and 5 items in a queue. Thinking about the underlying structure (i.e. the array) holding the data, what happens when you remove one item from the stack and one item from the queue? import java.util.EmptyStackException; public class ArrayStack implements Cloneable { private int[ ] data; private int manyItems; public ArrayStack( ) { final int INITIAL_CAPACITY = 10; manyItems = 0; data = (int[]) new int[INITIAL_CAPACITY]; } public ArrayStack(int initialCapacity) { if (initialCapacity < 0) throw new IllegalArgumentException ("initialCapacity too small " + initialCapacity); manyItems = 0; data = (int[]) new int[initialCapacity]; } public ArrayStack clone( ) { // Clone an ArrayStack. ArrayStack answer; try { answer = (ArrayStack) super.clone(…
- Note : addqueue works like Enqueue and deleteQueue works like Dequeue Consider the following statements: (8, 9) queueType queue; int num; Show what is output by the following segment of code num = 7; queue.addQueue (6); queue.addQueue (num); num = queue.front (); queue.deleteQueue(); queue.addQueue (num + 5); queue.addQueue (14); queue.addQueue (num queue.addQueue (25); queue.deleteQueue (); 2); cout <« "Queue elements: "; while (!queue.isEmptyQueue ()) { cout <« queue.front () << " "; queue.deleteQueue(); } cout <« endl; Queue elements: 14 14 4 25 Queue elements: 11 14 4 4 Queue elements: 11 14 4 25 Queue elements: 11 14 25 25Front and rear pointers are tracked in the linked list implementation of a queue. During insertion into the EMPTY queue, which of these pointers will change? (A Both front and rear pointer B Only front pointer Only rear pointer (D No pointer will be changedQueue 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.
- A(n) array can be used in an array implementation of a queue to avoid an overflow error at the rear of the queue when the queue is not full.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).What is the primary benefit of utilising a linked list instead of an array to construct a queue?
