Some nice monadic code patterns going on there, passing the cache around! (You might want to look into the State monad if you haven’t come across it before)

Thank you for the hint, I wouldn’t have recognized it because I haven’t yet looked into it, I might try it this afternoon if I find the time, I could probably put both the Cache and the current stone count into the monad state?

Your code as it stands is basically State BlinkCache written out explicitly, which is I think a natural way to structure the solution. That is, the cache is the state, and the stone count is the (monadic) return value. Good luck!
