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

The processes are assumed to have arrived as it shown in the table.

a$)$ Using the presented time axis draw Gantt chart that illustrates the execution of these processes using a

nonpreemptive S$.$JF $($the shortest$-$job$-$first$)$ scheduling $[1\mathrm{.}0$ credits$].$

b$)$ What is the waiting time of each process for the scheduling algorithms in part $($a$)$ and what is the average

waiting time? $[2\mathrm{.}0$ credits$]$

Finish writing of an example of the pseudo$-$code with a critical section $($you have to enter the missing value or

expression instead of dots.$).$ The critical section in the example is controlled by the so$-$called hardware support$-$

'disable$/$enable interrupts. Demonstrate that this example guarantees a condition of mutual exclusion.
