Java: Which operation is not supported in constant time by a double‐ended queue (deque)? Multiple choice. Insertion at the front or rear item Access and deletion of the minimum item Deletion of the front or rear item Access of the front or rear item

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…

What values are returned during the following sequence of queue operations, if executed on an initially empty queue? Enqueue(5) 1. 2. Enqueue(3) 3. Enqueue(2) 4. Dequeuel) 5. Enqueue(1) 6. Dequeuel) 7. Dequeuel) 8. Enqueue(4) 9. Dequeuel) 10. Dequeuel)

Problem 7: Assume that a queue class called XQueue has a no argument constructor, an enqueue() method, a dequeue() method and an isEmpty() method. Write a method that merges two given queues by copying the elements in an alternating sequence and returning the resulting combined queue. Note: make sure that you don't include unnecessary spaces in your answer! public XQueue merge(XQueue q1, XQueue q2) { XQueue neWQueue = new XQueue(); while (!q1.isEmpty() && !q2.isEmpty()) { newQueue.enqueue( #01 ); newQueue.enqueue( #02); } while (!q1.isEmpty()) { #03 ; } while (!q2.is Empty()) { #04 ; } return newQueue (); }

Given the following queue, which pointer points to the new item when the operation studentsQueue.Queue(new Item) is executed? This queue implementation removes from head when Dequeue is called. studentsQueue head: data: Tom data: Sam data: Tim tail: next: null next: next:- new Item data: Hal null next:- The studentsQueue head pointer Node Tom's next pointer The null pointer Node Tim's next pointer

Java: Which of the following operations has the least running time in a Queue (assume that only Queue interface operations are available; some operations may require use of an additional temporary  queue)? Multiple choice. Deleting the element at the rear of the queue Checking if an element x is present in the queue Finding the number of elements in the queue all of the above have identical worst case running time

Which of the following is the one that will most likely not be processed when a queue is terminated? What prompted the decision to remove it from general circulation?

Please help me with this! During the Battle at the Alamo, a the defenders suddenly discovered they are surrounded by an overwhelming force. There is absolutely no hope for victory without reinforcements, and David Crockett's horse is the only horse available that can be used to escape and summon help. The defenders agree to a pact to determine which of them is to go for help. The defenders form a queue and they pick a number from a hat. Beginning with the first officer in the queue, they begin to count. As each defender counts off, he moves to the end of the queue. When the count reaches the number that was picked, that defender is removed from the queue, and the count begins again with the next man. Once an defender is removed from the queue, he is no longer counted. The last defender that remains in the queue is the one that rides away on the horse to summon help. —————————— The countOff() method displays the name of each officer removed from the queue, in the order in which they…
