The following processes are being scheduled using a preemptive, priority-based, round-robin scheduling algorithm.

 Process Priority Burst Time Arrival Time P1 8 15 0 P2 3 20 0 P3 4 20 20 P4 4 20 25 P5 5 5 45 P6 5 15 55

Each process is assigned a numerical priority,with a higher number indi-cating a higher relative priority. The scheduler will execute the highest-priority process. For processes with the same priority, a round-robin scheduler will be used with a time quantum of 10 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.

b) What is the turnaround time for each process?

c) What is the waiting time for each process?
