write a c program below.

Ques. Design a scheduler with multilevel queue having two queues which will schedule the processes on the basis of pre-emptive shortest remaining processing time first algorithm (SROT) followed by a scheduling in which each process will get 2 units of time to execute. Also note that queue 1 has higher priority than queue 2. Consider the following set of processes (for reference)with their arrival times and the CPU burst times in milliseconds. -------------------------------------

Process Arrival-Time Burst-Time -------------------------------------

P1 0 5

P2 1 3

P3 2 3

P4 4 1

-------------------------------------

Calculate the average turnaround time and average waiting time for each process. The input for number of processes and their arrival time, burst time should be given by the user.
