Since all operations increase the accumulator, I tried putting a
guard (a <= x)inapply, but it doesn’t actually help all that much (0.65s -> 0.43s).0.65 -> 0.43 sounds pretty strong, isn’t that a one-fourth speedup?
Edit: I was able to achieve a 30% speed improvement using this on my solution
It’s not insignificant, sure, but I’d prefer 10x faster :D
Plus I’m not sure it’s worth the loss of generality and readability. It is tempting to spend hours chasing this kind of optimization though!
