For the processes listed below, draw a Gantt chart illustrating their execution using priority scheduling for: (a) Preemptive (b) Nonpreemptive cases. A larger priority number has higher priority.

Also calculate the turnaround time, wait time for the algorithms and average throughput for each of the algorithms.

Process Arrival Time Burst Priority A 0.0000 4 3

B 1.0001 3 4

C 2.0001 3 6

D 3.0001 5 5
