-- What does this do?
-- Notice that we had to convert the number result of length to a String with show

output4 = "\t" ++ show ( length (lines input))
    ++ "\t" ++ show ( length (words input))
    ++ "\t" ++ show (length input)
output4 = "\t" ++ show ( length (lines input))
    ++ "\t" ++ show ( length (words input))
    ++ "\t" ++ show (length input)
output4 = "\t" ++ show ( length (lines input))
    ++ "\t" ++ show ( length (words input))
    ++ "\t" ++ show (length input)
