Re: [Haskell-beginners] Pattern matching with one, two or more arguments

Another trick : how can i calculate consonnes with a method that makes the difference between  the two lists [a..z] and  voyelles, rather  than writing each consonant. As we can append two lists (++), can we compute the difference between lists, i.e. delete from the first list the elements that are present in the second one ?

Use Data.List.\\ ['a'..'z'] \\ "aoeui" ==> "bcdfghjklmnpqrstvwxyz" -- Deniz Dogan
