Scheduling. Three batch jobs, A through E, arrive at a computer center at almost the same time. They have estimated running times of 10, 6, 2, 4 and 8 minutes. Their priorities are 3, 5, 2, 1 and 4 respectively, with 5 being the highest priority. For each of the following scheduling algorithms, determine the mean turnaround time. Ignore any process switching overhead.
a) Round Robin
b) Priority Scheduling
c) First Come, first served (run in order A, B, C, D, E)
d) Shortest job first
