    * Couldn't match type `[b0]' with `Int'
      Expected type: String -> Int
        Actual type: String -> [b0]
    * In the second argument of `(.)', namely `map read . words'
      In the second argument of `(.)', namely

    * Couldn't match expected type `Int -> [Int]'
                  with actual type `[a0]'
    * The function `tail' is applied to two arguments,

    * Couldn't match expected type `[a0]'
                  with actual type `Int -> [Int]'
    * Probable cause: `solve' is applied to too few arguments
      In the first argument of `tail', namely `solve'

      In the second argument of `(:)', namely
