2. Consider the following set of processes, with the arrival times and the length of the CPU burst times given in milliseconds, and the priorities given so that smaller priority number means a higher priority.

(3) nonpreemptive priority. We specify that when a preempted process and new coming process need to be put in the ready queue at the same time, we prefer to 315
