Suppose that a disk drive has 6,000 cylinders, numbered 0 to 5999. The drive is currently serving a request at cylinder 2150, and the previous request was at cylinder 1105. The queue of pending requests, in FIFO order, is:

2629, 3722, 2805, 3192,773, 1939, 1296, 1918, 5730, 2152, 1356

Starting from the current head position, what is the total distance (in cylinders) that the disk arm moves to satisfy all the pending requests for each of the following disk-scheduling algorithms?
Show the calculation result (10 points)
Show the sequence of the position of the head and calculation steps (20 points)
