Problem $1[40$ pts$]$

Consider the following processes:

$\backslash$table$[[$Process$,$Arrival Time,Service Time$],[$A$,0,3],[$B$,1,1],[$C$,3,3],[$D$,4,2],[$E$,5,5]]$

Show how the above processes execute over time on a single CPU system $($i$.$e$.,$ please draw the schedule where the $x-$axis is the time$).$ Compute the completion time for each process, and the average turnaround time for all processes under each of the following schedulers:

$($a$)$ FCFS$.[8$ pts$]$

$($b$)$ Round Robin with
