consider an array based queue implementation. suppose we wish to use an extra bit in the queue records to indicate whether a queue is empty.

c) Given a Python Queue class implemented with the abstract data type (ADT) below, write a new method popqueue(), which will “pop" (remove and return) the last-in element from the rear end of the queue. | Operation (Queue) Description sizeQ():int | GIVEN: Get (and return) the size of the queue (total number of elements) enqueue (elt): dequeue (): elt popqueue(): elt Remove (and return) the last-in element from rear end of Queue GIVEN: Insert elt into Queue GIVEN: Remove (and return) element from Queue Finish this new Python popqueue () method, by completing the method body below: def popqueue ( self ): # remove and return rear elt # body of the method. TO BE COMPLETED by student o No other extra variable could be added including Python's list, except int and range with function range(). o No more than 4 lines of typical python code (without semicolon symbol ;) allowed in the method body. * Hint: you may finish this task using its own given methods of the Queue class, and a for loop…

7. Given a Queue Q, write a non-generic method that finds the maximum element in the Queue. You may use only queue operations. No other data structure can be used other than queues. The Queue must remain intact after finding the maximum value. Assume the class that has the findMax method implements Comparable. The header of the findMax method: public Comparable findMax(Queue q)

Create an implementation of each LinkedList, Queue Stack interface provided For each implementation create a tester to verify the implementation of thatdata structure performs as expected Your task is to: Implement the LinkedList interface ( fill out the implementation shell). Put your implementation through its paces by exercising each of the methods in the test harness Create a client ( a class with a main ) ‘StagBusClient’ which builds a bus route by performing the following operations on your linked list: Create (insert) 4 stations List the stations Check if a station is in the list (print result) Check for a station that exists, and one that doesn’t Remove a station List the stations Add a station before another station. List the stations Add a station after another station. Print the stations StagBusClient.java package app;  import linkedList.LinkedList; import linkedList.LinkedListImpl; public class StagBusClient { public static void main(String[] args) { // create…

A stack-ended queue, sometimes known as a steque, is a data type that allows push, pop, and enqueue operations. Make an API for this ADT. Create a linked-list implementation.

Java Algorithm Programming Question Implement the ADT queue by using a circular linked list. Recall that this list has only an external reference to its last note. Example Output: Create a queue: isEmpty () returns true Add to queue to get Joe Jess Jim Jill Jane Jerry isEmpty () returns false Testing getFront and dequeue: Joe is at the front of the queue. Joe is removed from the front of the queue. Jess is at the front of the queue. Jess is removed from the front of the queue. Jim is at the front of the queue. Jim is removed from the front of the queue. Jill is at the front of the queue. Jill is removed from the front of the queue. Jane is at the front of the queue. Jane is removed from the front of the queue. Jerry is at the front of the queue. Jerry is removed from the front of the queue. The queue should be empty: isEmpty() returns true Add to queue to get Joe Jess Jim Testing clear: isEmpty() returns true Add to queue to get Joe Jess Jim Joe is at the front of the queue. Joe is…

Your crazy boss has assigned you to write a linear array-based implementation of the IQueue interface for use in all the company's software. You've tried explaining why that's a bad idea with logic and math, but to no avail. So - suppress your inner turmoil and complete the add() and remove() methods of the AQueue class and identify the runtime order of each of your methods. /** A minimal queue interface */ public interface IQueue { /** Add element to the end of the queue */ public void add(E element); /** Remove and return element from the front of the queue * @returns fırst element * @throws NoSuchElementException if queue is empty */ public E remove(); /** Not an ideal Queue */ public class AQueue implements IQueue{ private El) array: private int rear; public AQueue(){ array = (E[)(new Object[10]): rear = 0: private void expandCapacity) { if (rear == array.length) { array = Arrays.copyOf(array, array.length 2): @Override public void add(E element) { / TODO @Override public E…
