How are there submissions that are under 90 seconds?
I was looking through the global leader board for day 3 today and noticed that the first 100 results are all under 90 seconds, with the top 4 being under 30 seconds. How is that possible? What are people leveraging in order to accomplish this?
Professional code golfers (Is that the right term?) build up a large suite of helper libraries from past events/from daily puzzle solving that they invoke for common problem types like graph search or constraint solving.
I assume the most difficult aspect of the problems is to translate the statements into actual code constraints/filter functions. So the spirit of the competition is not broken by having pre-written code (Although I am not sure many would think pre-written code is acceptable).
