Question
  1. The following processes are being scheduled using a preemptive, priority-based, round-robin scheduling algorithm.

    Each process is assigned a numerical priority, with a higher number indicating a higher relative priority. The scheduler will execute the highest-priority process. For processes with the same priority, a round-robin scheduler will be used with a time quantum of 10 units. If a process is preempted by a higher-priority process, the preempted process is placed at the end of the queue.

    Fill in the multiple blanks.

    a. What is the turnaround time for each process? 

    P1 = , P2=  , P3 =  , P4 =  , P5 =  , P6 = 

    b. What is the waiting time for each process?

    P1 = , P2=  , P3 =  , P4 =  , P5 =  , P6 =
