My code is in Haskell and I presume there might be something wrong with random tests of this problem. I think my code is fine but I got this error "Falsifiable (after 25 tests):
Positive {getPositive = 10}", and I have no idea what it is for. That'd be greatly appreciated if someone can help me out here.
