Checking the sample code

    if d = 0 then "0"
    else

        if digit = 0 then acc
        else aux (string_of_int (d land 1) :: acc) (d lsr 1) (digit - 1)
    in
    String.concat "" (aux [] d 7)
in

let m = (input_line stdin) in
let c = [|"00"; "0"|] in
let b : string ref = ref "" in
for i = 0 to (String.length m) - 1 do
    b := !b ^ (bin_of_int (Char.code m.[i]));
done;
