The items in the returned array should be sorted alphabetically, with numbers before strings.

It's called: CHAR_TO_MORSE

Javascript: //CHAR_TO_MORSE preloaded to convert characters into Morse code.
Ruby: #$CHAR_TO_MORSE preloaded to convert characters into Morse code
Pyhton: #CHAR_TO_MORSE preloaded to convert characters into Morse code
