Input the number of processes required to be scheduled using
FCFS, burst time for each process and its arrival time.
Using enhanced bubble sort technique, sort the all given
processes in ascending order according to arrival time in a
ready queue.
Calculate the Finish Time, Turn Around Time and Waiting Time for
each process which in turn help to calculate Average Waiting
Time and Average Turn Around Time required by CPU to schedule
given set of process using FCFS.
