$8.$ We have two processes P$1$ and P$2$ with p$1=40,$ t$1=15,$ p$2=80,$ t$2=30.$ The deadline for each process requires that it complete its CPU burst by the start of its next period $($the same as in examples shown in lecture$).$ u If so$,$ give the schedule for the first few periods. $($Use the same format as your answer to the previous question.$)$
