So if you did check for integers or some other really wacky input, you are a more thorough and diligent programmer than I am. Good work, but I was really only worried about strings here. Just as an upfront check, I go through every character in hexNum and just make sure that it's in our dictionary up here. And if it is in our dictionary, then I know I can process it.
