When an element is removed from a queue, where is it removed from?

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 25

from PlaneQueue import PlaneQueue from PlaneNode import PlaneNode   if __name__ == "__main__":     plane_queue = PlaneQueue()          # TODO: Read in arriving flight codes and whether a flight has landed.      # Print the queue after every push() or pop() operation. If the user     # entered "landed", print which flight has landed. Continue until -1      # is read.

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.

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.

Explain the differences between a statically allocated array, a dynamically allocated array, and a linked list.

The tail of a linked list is distinguished from other nodes because its next pointer is:A. void B. empty C. NULL D. None of the above.
