Consider the following set of processes, with the length of the CPU burst and arrival time given in seconds:

Process	Arrival Time	Burst Time
P2	0	12
P3	3	8
P4	5	4
P1	10	10
P5	12	6

• Draw Gantt chart that illustrate the execution of these processes using theShortest Remaining Job First (SJRF) a.k.a preemptive Shortest Job First.
• What is the turnaround time of each process?
• What is the waiting time of each process?
• What is the Averageturnaround time of the execution?
•  What is the Averagewaiting time of the execution?
