Problem 11.3. Consider a disk drive with 4000 cylinders, numbered from 0 to 3999. The request queue has the following composition: 1045 750 932 878 1365 1787 1245 664 1678 1897 If the current positions is 1167 and the previous request was served at 1250, compute the total distance (in cylinders) that the disk arm would move for each of the following algorithms a: FIFO b: SSTF c: SCAN d: C-SCAN
