@taigrr Forget it. 🤣 I’m writing all this in C with DOS compatibility in mind. If I happen to be faster than you, then it’s just sheer luck. 😅

@taigrr Well, consider yourself the winner, I guess. Today’s puzzle was super annoying (to me), so I turned to reddit for help.

Ha, I *did* get it to work on DOS! I only have about 3.9 kB of stack size available, which is very little for all the recursion that we’re doing today. As a last resort, converting recursion to iteration might have been an option, but I managed to keep the stack usage small enough (about 3.5 kB).

That was a tough one …

Nice! glad you got it in the end. I was at an event put on by the Linux Foundation yesterday and missed out on the problem, only got to it tonight after doing day 14 😥

But tonight was also YSBEUC9jYWNoaW5nIHByb2JsZW0gYW5kIHlvdSBnb3QgaXQgbm8gcHJvYmxlbSEK !!

@taigrr Yeah, I got it. 😅 After some optimization, it runs on DOS. Needs about half the available memory (~250 kB used).
