    Here is how to read the stdin for this question in Ocaml:

    let f n arr = 
    (* implementation *)
    
let () =
    (* first line is parsed as the first arg to f *)
    let num = int_of_string (read_line ()) in
    
    (* the rest until EOF are parsed into an array for second arg *)
    f num (
        let rec aux arr =
            try
                let input = read_line () in
                    match input with
                    | "" -> arr
                    | a  -> aux (arr @ [int_of_string a])
            with End_of_file -> arr
        in aux [] )
