Operating system

Consider the following set of processes, with the length of the CPU burst given in milliseconds: (36 points) Four kinds of scheduler should be performed in the system. There are FCFS, preemptive shortest-remaining-time-first, non-preemptive shortest-remaining-time-first, and preemptive RR (quantum time is 4 milliseconds). What are the average waiting time, turnaround time and response time of these schedulers
