[Haskell-cafe] testing for same characters in lists of strings

[Jackm139]

Thanks for all the replies!
I have it working somewhat.  It works as long as there is only one string in
each list, but if the lists contain more than one string it fails. here is
what I have:


import List

same :: [[Char]] -> [[Char]] -> Bool
same [xs] [ys] = map (normalize) [[xs]] == map (normalize) [[ys]]

normalize :: [String] -> [String]
normalize [xs] = [(sort (nub xs))]


How can I make this work for lists that contain more than one string?
