title: Determine what sorting algorithms are being used by a .jar?
body: <p>How does one go about determining the different types of sorting algorithms without being able to look at code?</p>
  
  <p>The scenario is that our lecturer showed a .jar file with 4 sorting methods in it (sortA, sortB...) that we can call to sort a vector.</p>
  
  <p>So, as far as I know, we can only measure and compare the times for the sorts. What's the best method to determine the sorts?</p>
  
  <p>The main issue is that the times for the sorts don't take very long (differing by ~1000ms) to begin with, so comparing them by that isn't really on option, and so far all the data sets I've used (ascending, descending, nearly sorted) haven't really been giving much variation in the sort time.</p>
