On a disk with 1000 cylinders (0 to 999) find the number of tracks, the disk arm must move to satisfy all the requests in the disk queue. Assume the last request service was at track 345 and the head is moving toward track 0. The queue in FIFO order contains requests for the following tracks:

123, 874, 692, 475, 105, 376

Perform the composition for the following scheduling algorithm:- i.FIFO ii.SSTF iii.SCAN iv.C-SCAN
