answer question c

4. Suppose that a disk drive has 5000 cylinders, numbered 0 to 4999. The drive is to currently serving a request at cylinder 143, and the previous request was at ASU cylinder 125. The queue of pending requests, in FIFO order, is 86, 1470, 913, 1774, 948, 1509, 1022, 1750, 130 od TOT 9700 Starting 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 do following disk-scheduling algorithms?
