Let the processes P1, P2, P3, and P4 be given. They arrive in the system at the same time in this order. The processes have the following service times (in time units): Process Service time (CPU burst) P1 53 P2 17 P3 68 P4 24 2) For the scheduling method "Round Robin" (RR), specify the average execution time (average turnaround time) and the number of context switches. The time quantum q is set to 20 time units. You must show your calculations. You will not have to draw Gantt charts. Note: For RR, processes execute in order of their ID (i.e., P1-P2-P3- P4).

Compute and print the completion Time(CT), Turnaround Time(TAT), and Waiting Time(WT) for each process using C Programming. Waiting time: Processes need to wait in the process queue before execution starts and in execution while they get preempted. Turnaround time: Time elapsed by each process to get completely served. (Difference between submission time and completion time).
