title: What's the difference between non preemptive SJF and preemptive SJF [C]
body: <p>I have the code for non-preemptive SJF working perfectly but I just want to know is there a big difference between preemptive and non-preemptive? Like would the code be completely different and would the turn around time be different between the two ?</p>
  <ul>
  <li>Created non-preemptive SJF</li>
  <li>Attempted creating preemptive SJF (Does this just mean arrival times are visible or?)</li>
  </ul>
