Hi Glenn! Basically for this challenge, I don't think it'll happen, even if I do revisit these and start improving them. Sorry. I can, if I do revisit this, pretty much promise I can tighten up the description though.
More of an explanation below, which I hope helps!
Checking for specific answers in this case wouldn't work all that well, as there are literally an infinite number of them; we'd have to come up with a way to check the output, and a reasonable way to also make sure the a loop was used (probably just by overwriting
num to another value and ensuring it worked).
That type of testing for this challenge probably isn't in place, so although possible (done for other challenges), I'm pretty sure it'd be reasonably tough.
I'd have no problem taking a crack at it, but there are other more important things to improve in these course's challenges; my or dev's time is better spent elsewhere, save for improving the description.
Oh, and I don't know if the videos and challenges were done in concert. Some do really have a tough time as the videos for sure don't cover exactly what's in the challenges. The concepts for sure, but not the specific. Please do ask here if you need any help figuring things out!
