2. [15 marks] Consider the same 7 processes with arrival time and CPU burst time in second again. But now we also assign a priority for each task, where 1 represents the highest priority while 4 represents the lowest priority. Process Arrival time P1 P2 P3 P4 P5 P6 2 tt 8 P7 7 9 11 13 8 2 CPU burst time 3 5 1 Priority 2 2 1 3 1 Construct a table to illustrate the execution of these processes under the preemptive priority scheduling method.
