On a disk with 1000 cylinders, numbers 0 to 999, compute the number of tracks the disk arm must move to satisfy all the requests in the disk queue. Assume the last request serviced was at track 345 and head is moving to track 0. The queue in FIFO order contains requests for the following tracks: 128, 870, 694, 470, 107, 378. Show the disk arm movement and calculate the number of tracks traversed using the following policies:
(a) FIFO (b) SSTF (c) SCAN (d) LOOK
