Calculate please. operation system question

Question 3 (12 marks) Consider a disk drive with 2000 cylinders, numbered from 0 to 1999. The request queue has the following composition: 656 1145 827 902 1234 458 1164 1688 1024 517 If the current position of the disk head is 800, and the previous position is 900, list the order of requests that are served, find the number of tracks traversed by the disk head upon serving each request, and hence compute the total number of tracks traversed and the average seek length, for each of the following algorithms: FIFO, SSTF, SCAN and C-SCAN scheduling
