Draw four Gantt charts illustrating the execution of these pro- cesses using FCFS, SJF, a nonpreemptive priority (a smaller pri- ority number implies a higher priority), and RR (quantum 1) b. What is the turnaround time of each process for each of the scheduling algorithms in part a? What is the waiting time of each process for each of the scheduling algorithms in part a? c. d. Which of the schedules in part a results in the minimal average 2 waiting time (over all processes)
