mymin x y = if x<y then x else y

{- Which are correct types for mymin?  Which is the most general type
  (if any)?

mymin :: Ord n => n -> n -> n
mymin :: n -> n -> n
mymin :: Eq n => n -> n -> n
mymin :: Int -> Int -> Int
mymin :: String -> String -> String

and a trick question:
mymin :: Num n => n-> n -> n


You can test your answers first by asking Haskell for the most general type:
:t mymin

and then testing different types:
:t mymin :: Int -> Int -> Int
