Question 1 Analyze the following code: import java.util.*; public class Test { public static void main(String[] args){ PriorityQueue queue = new PriorityQueue( Arrays.asList (60, 10, 50, 30, 40, 20)): while (!queue.isEmpty ()) System.out.print(queue.poll () + " "); The program displays 10 20 30 40 50 60 O The program displays 60 50 40 30 20 10 O The program displays 60 10 50 30 40 20 There is no guarantee that the program displays 10 20 30 40 50 60

b. Write out the order of elements that are contained in a queue after the following operations are performed. myQueue.enqueue(new Integer(16)); myQueue.enqueue(new Integer(12)); Integer num1 = myQueue.dequeue(); myQueue.enqueue(new Integer(6)); myQueue.enqueue(new Integer(8)); myQueue.enqueue(new Integer(30)); myQueue.enqueue(new Integer(24)); myQueue.enqueue(new Integer(18)); myQueue.dequeue(); myQueue.dequeue(); myQueue.dequeue(); myQueue.enqueue(new Integer(38); Show how step by step process of arriving at your answer.

print the even numbers followed by ödd oh Ex4) Given the file pointerlmofQueue.java then write a main method: to - add some elements into the queue, - reverse the queue contents, (Hint use an array) - print the queue contents.

DONT use any of the list methods (append, pop etc.). class mycircularqueue():        def __init__(self, m = 10):        self.maxsize = m        self.array = [None]*m        self.FRONT = self.REAR = -1                def enqueue(self, item):         # Inserts item at the rear of a non full queue and returns True. If unable to insert the item returns false                #######################################################################        # Remove the pass statement and write your code        #######################################################################        pass     def dequeue(self):        # Removes the item from the front of the queue and returns it. For unsuccessful dequeue return False                #######################################################################        # Remove the pass statement and write your code        #######################################################################        pass        def peek(self):        # Returns the…
