RegEx inspired by MarqueeCrew
One tool one formula solution
Definitely had to search my memory for the appropriate character class for this one, because I rarely use it! In fact, the last time I used it, I think, was a previous weekly challenge!
I saw that @MarqueeCrew posted this on Twitter over the weekend, and finally got a chance to read/watch. Definitely check out the post and watch the video! Lots of good general tips in the video, not just related to solving this particular challenge.
Pretty sure I oversimplified this one.
I oversimplified and ignored uppercase. Thanks for the video and blog to help me better understand the Regex and the expressions along with you original solution, I'm saving both. 🙂
