Compute number of disk tracks traversed by using fcfs-sstf

Reference no: EM1383288

Compute number of disk tracks traversed by using FCFS, SSTF, SCAN, and LOOK algorithms for series of disk track service request given below. At time first request arrives in disk request queue, read/write head is at track 50, moving toward outer (lower-numbered) tracks and total number of track is 100 (numbered as 0 to 99).
54, 36, 21, 74, 46, 36, 26, 67

Each track over which disk arm passes counts in total, whether or not track is read.
