thoughts

I found this really tough for a day 1 problem. Because I don't really know regex, I did not know the secret to finding overlapping patterns. I quickly figured out that "twone" was a possibility, because it was in the example, but then I had to find other examples and hardcode them into my split pattern.

This isn't general, my input doesn't have 'sevenine' for example.
