A MLF algorithm uses $5$ priority levels. At level $5,$ a process executes for Q $=1$ ms$.$ At each of the lower levels the quantum is doubled $(2$Q$,4$Q$,8$Q$,16$Q$).$ The following processes are to be scheduled: After termination, process p$1$ blocks for $4$ ms and then reenters the queue again at level $5.$ Similarly, process p$2$ blocks for $5$ ms and then reenters the queue again at level $5.$ Process Arrival Total CPU time P$101$ P$215$ a$.$ Draw a timing diagram for the first $10$ ms$.$ On each of the $2$ lines $($one per process$)$ show when the process is running and at which priority level. b$.$ Determine the ATT for each process.
