Question 9: Draw internal representation of the queue q for each step of the following code: ArrayBoundedQueue<Integer> q = new ArrayBoundedQueue<Integer>(6); q.enqueue(37); q.enqueue(86); q.enqueue(54); q.enqueue(71); q.dequeue(); q.enqueue(97); q.dequeue();

Let's say your current programming project is using a circular queue implementation which uses a simple modulus operation for moving the head and tail forward: p = (p+1)%n. But the queue isn't a purely traditional one and you sometimes have to move backwards during a search. When this search wraps from the front to the rear, you must use this code: p = (p==0?n-1:p-1). One day programmer Sam comes up with this little gem: p=(p+d)%n. Here d is filled in with 1 when moving forward and n-1 when moving backwards. Can Sam's simple solution be correct? Prove or disprove Sam here.
ALL TRUE OR FALSE QUESTIONS 1. The text's array-based queue implementations use the fixed-front approach. 2. The enqueue and dequeue queue operations are inverses of each other. Therefore, performing an enqueue followed by a dequeue is always equivalent to performing a dequeue followed by an enqueue. 3. It is possible to implement an unbounded queue using an array-based approach. 4. Our QueueInterface defines two constructors. 5. The isEmpty operation as defined for the text's Queue ADT might throw the QueueUnderflowException. 6. A "dequeue" allows an application to peek at the front of rear values of a queue. 7. A java interface can inherit from at most one other interface. 8. The main thread of a Java program cannot generate additional threads. 9. Code sequences in concurrent programs never interfere with each other.

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…
