Consider the following set of processes, with the length of the CPU burst time given in milliseconds:

The processes are assumed to have arrived in the order P1, P2, P3, P4, P5, all at time 0.

a. Draw two Gantt charts that illustrate the execution of these processes using the following scheduling algorithms: nonpreemptive priority (a smaller priority number implies a higher priority), and Round-Robin (quantum = 1).

b. What is the turnaround time of each process for each of the scheduling algorithms in part a?

c. What is the waiting time of each process for each of these scheduling algorithms?
