SAMPLE INPUT AND OUTPUT:

Enter howmany jobs:5

Enter burst time for corresponding job....

Process 1:4

Process 2:2

Process 3:8

Process 4:2

Process 5:9

process 1 waiting time is 0
Process 2 waiting time: 4
Process 3 waiting time: 6
Process 4 waiting time: 14
Process 5 waiting time: 16
total waiting time:40.000000

the average waiting time is:8.000000
