Leetcode 75

In the true yak-shaving tradition, I want to build a quick webscraper that takes all the links in the LC75 page and then prints them to PDF. From there, I can view them on my remarkable, so I can be a way from my computer and study them with pen and paper.

Leetcode provides validation of solutions, which is nice. But having a format that distills the problems into something offline for reference would be nice.

I think I might just manually transcribe the questions to markdown and put them in a repo.

I am putting it in "main" instead of priority.

Let me get these last few projects in a good place (demo-trio and dagzet-rust), and then I'll try to find time to start this?

I know, I know. I'm putting it off.

1448. I gave up and looked it up. I was in the right direction with the recursive answer. C++ classes in the solution made it much easier. count was essentially kept as a global. When I didn't have to think about keeping track of that varibale in a recursive function, the problem and code got a lot easier to reason with. Lesson learned.

At this point, I have attempted about half the problems of LC75. I think I've chewed through most of the easy problems that I could do quickly. What remains are the sorts of problems I'll need to do more research into. I'm ready to slow down with these and change gears a little bit.
