    It seems haskell is broken:

    main = print "Hello World"

    Your Output (stdout) "Hello World" Expected Output Hello World

      print -> putStrLn. You should not print ".

        thanks! Than it would make sense to fix https://www.hackerrank.com/challenges/fp-solve-me-first and use putStrLn there as well, because it is confusing.

          Hi @aindl, for string type putStrLn should be preferred. While for non-string types you need to convert it into a string and then use putStrLn on it, and print is doing that for us. Check the difinition of print

          print = putStrLn. show

      The valid syntax is:

      main = do
  putStrLn "Hello World"

    beginner OCaml student here, I'm teaching it myself. I don't seem to have problem defining functions for variables (in the classic OO-sense), but I am having problem with stdin/stdout in OCaml. I try to define inputString as read_line, then output the string literal "Hello, world" and then the inputString, but only "Hello, world" is printing. I'm not too sure what is going on.
