1 a. Draw the Gantt chart and calculate the waiting and turnaround times for each process using a FCFS scheduling algorithm.

b. Draw the Gantt chart and calculate the waiting and turnaround times for each process using a SJF scheduling algorithm. [SRTF: Shortest Remaining Time First]?

c. Draw the Gantt chart and calculate the waiting and turnaround time for each process using a preemptive priority scheduling algorithm? [a smaller priority number implies a higher priority]
