Review comment:
       Ah ok. I was just wondering about the formatting of the final string. 
Anytime I see a `toString` call, I get a bit suspicious. It was the leading `0` 
before the X that threw me off.
   
   But in this area, it is indeed the correct way to go. And it does appear 
that your unit tests are passing and you're using the expected spark literal 
syntax there. Thanks for the explanation. 👍
