Given the program segment below: QueuecInteger queue new LinkedListcInteger int element 1 s 1, element2=0; element3-4; queue.enqueue(element2): 0 queue.enqueue(elementI); queueenqueue(elementl + element3): 4h: element2 squeue.dequeue(); queue.cnqueue element3 * element3);h: S queue.enqueue(element2): element1 queue.dequeue( ); System.out.printIn(elementi + " + +element element3): " + 4 while (queue.isEmpty) 5 element 1 = queue.dequeue( ); 3. Suppose that queue is a QueueClass object and the size of the array implementing queue is 100. Also, suppose that the value of queueFront is 99 and the value of queueRear is 25 i) What are the values of queucFront and queueRear after adding an element to queue? queueFront queueRear25 (i) What are the values of queucFront and queucRear after removing an element from queue? queueFront = queueRear =
