I've always hated these kinds of problems because I'm so terrible at them, yet they have a strange appeal to me - like a magic trick I can't figure out. After clicking on a few of the solutions, I discovered that the even the solutions aren't very helpful for me. What would be cool is a video where two people talk through how to think about coming up with solutions, white boarding as necessary. Maybe these specific problems are too advanced to be explained in a way accessible to the math-challenged. If anyone knows of a resource that starts with these kinds of relatable problems but then thinks different approaches through out loud, I'd love a link.
