Consider a disk system with 200 cylinders. {0-199} the requests to access the cylinders occur in the following sequence: 3, 33, 9, 6, 18, 72, 1, 14, 5, 19.
Assuming that the head is currently at cylinder 50, and it takes 1 ms to move from one cylinder to adjacent one. Which of the following policy will take second highest time to satisfy all the request?
