Instead of == you can use pattern-matching. isgood :: String -> Bool isgood = isValidFinal . foldM (check . step) (0, 0) where step (x, y) 'R' = (...

Curious, this code looks a lot like the code in this question. I'm not saying that you have another account, but you don't happen to be in the same class or something? Your formatting seems to be inconsistent, use an automatic code formatter (your IDE most likely has one). private static final Scanner SC = new Scanner(System.in); Don't shorten names just ...
