The question isn't asking you to write a program. It is only asking you 
to sort the characters, and you've done that already.

When you learn about arrays, you'll learn about a method to sort it

"Lies" does not mean deception or falsehood here; "lies" means "is 
located". It is asking where the "?" is located in the ASCII table. Try 
running "?" < "0" on irb and let your truth value be your guide.
