IMHO every programer has a unique style to some extent, you just need to spend enough time looking at their code to start recognising those specific patterns. For some of my friends I can always guess that code is theirs by the way they name variables, how they structure the logic and other small details. So I guess you can just pick any elegant programming solution and try to replicate the logic on your own, and then compare it and see what they did differently.
