Suppose that a disk drive has 6,000 cylinders, numbered 0 to 5,999. The drive is currently serving a request at cylinder 2,150, and the previous request was at cylinder 1,805. The queue of pending requests, in FIFO order, is:2,069; 1,212; 2,296; 2,800; 544; 1,618; 356; 1,523; 4,965; 3,681Starting from the current head position, what is the total distance (in cylinders) that the disk arm moves to satisfy all the pending requests for each of the following disk-scheduling algorithms?

A.FCFS

B.SCAN

C.C-SCAN
