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.!
