Please ASAP, I will like. Please ASAP, I will like. Let the processes

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): \begin{tabular}{|l} P1 \\ \hline St \\ C \\ \hline \end{tabular} 1. (6 points) For the scheduling method "Shortest Job First" (SJF), specify the execution order of the processes, the average execution time (average turnaround time) and the average waiting time over all processes. You must show your calculations. You will not have to draw Gantt charts. 2. (4 points) 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)
