1. The processes typically will be assigned to the CPU based on the given scheduling algorithm. Suppose there are four processes and their arrival time, burst time, and priority are as shown in the following table. $(8\%)$ (a) What is the execution order and average time of these processes when using first-come, first-served (FCFS) scheduling algorithm? (b) What is the execution order and average time of these processes when using shortest-job-first (SJF) scheduling algorithm? (c) What is the execution order and average time of these processes when using priority-scheduling algorithm? (d) What is the execution order and average time for these processes when using round-robin (RR) scheduling algorithm? Note that each process will have a fixed time to execute in RR called a quantum which is set equal to 5 here.
