Suppose that a disk drive has 100 cylinders, numbered 0 to 99. The driver is currently serving a request at cylinder 14. The queue of pending requests is, in the order received: 1, 12, 9, 80, 81, 1, 82, 10, 42Starting from the current head position, what is the total distance (in cylinders) that the disk arm moves to satisfy all the pending requests for the following scheduling algorithms. 1. First come first serve, 2. SCAN (initially moving downwards)
