It seems elixir is broken

Dear Hackerrank Team Pls enable C/C++ Language in Functional Programming Section

Scala Code:

def f() = println("Hello World")

It seems haskell is broken:

main = print "Hello World"

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

-- fails at Submit with read STDIN hello_world = do input <- getLine putStrLn input

-- submit successfully hello_world = do putStrLn "Hello World"

in haskell

main = interact $ (\x -> "Hello World")

Lisp solution : (write-line "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.

object Solution{ def f():Any = {println("Hello World")} def main(args: Array[String]) { f() }

} does not work an i do not understand why?
