Hello

I have a file with 100 lists, with 100 ints.

I have to read the file and apply the map and sort functions on lists.

II did it to read file:

learquivo :: FilePath -> IO ([[Int]]) learquivo s = do            conteudo <- readFile s            return (read conteudo)

But now applying the sort, the error appears:

Where do you apply 'sort' ? You mean sort learquivo ? It must be fmap sort learquivo .
