    1. AIM: To write a C program to simulate the shortest job first algorithm with preemption. DESCRIPTION: For implementing SJF algorithm with preemption‚ we consider the arrival times of each process‚ the burst times of all the previously arrived processes. After the arrival of all the processes into the ready queue‚ the average waiting time and turn around time can be calculated by using the above algorithm. ALGORITHM: 1) start 2) read the no of processes to n 3) initialize i to 0 4) if
