is there any way i could get a hint at what im doing wrong? I could copy and paste my code here with a spoiler mark if it would help?

It's not an issue of the kata... You should try to speed up your program, it is possible to have something about 4200 ms.

So i'm doing this in haskell and all the test cases pass, but upon submitting it times out saying it took longer then 6000 ms. Any ideas why? Before when this happened it was due to some math trick i didn't know. Is that the case with this one? My algorthm wouldn't win any awards but it appears correct. :/
