The following processes are being scheduled using a preemptive, roundrobin

scheduling algorithm. Each process is assigned a numerical

priority, with a higher number indicating a higher relative priority.

In addition to the processes listed below, the system also has an idle

task (which consumes no CPU resources and is identified as I ). This

task has priority 0 and is scheduled whenever the system has no other

available processes to run. The length of a time quantum is 5 units.

If a process is preempted by a higher-priority process, the preempted

process is placed at the end of the queue.

a. Show the scheduling order of the processes using a Gantt chart.

Enter the times for the above chart starting with 0

b. What is the turnaround time for each process?
