So… what did I do? Sadly, essentially nothing. You see, I was working on creating a sudoku, and I thought I figured it out (all by myself – I was very proud). But no. I only realized after spending a dumb amount of time on my initial plan (of only generating the clues/initial filled squares) that it wouldn’t guarantee a solution. So now I’m back at square one, trying to figure out how to generate the entire puzzle and then remove values to create the starting hints. I have to figure out recursion, but I do not fully understand…
