(c).	Consider the disk arm is moving on a disk with 200 tracks. While retrieving data from Track 100, the following requests has arrived: Track 120, 55, 58, 39, 18, 90, 160, 150, 38, 184. Determine the seek order and the total seek time travelled by the arm when the following algorithms are used:
	(i).	Shortest Seek Time First (SSTF)
	(ii).	SCAN
	(iii).	C-LOOK
