Though I avoided using the list monad in the first solution, since
I thought it would make the code less understandable for a beginner.
I felt uncomfortable seeing this. Let me see if I can explain why.
Isn't the use of monads here unnecessary and obscure? The use of
inits, tails and maximumBy ground the function to a list
representation. There seems no hope of generalizing it to other
monads. The use of >>= is just an obscure way of saying (flip
concatMap).
