@xuu Yes, exactly that. *But*: I do have more than 32 bits after all, when I use `double` or `long double`. 😲 I went with `long double` which has 80 bits even on DOS (63 bits mantissa, I think).
(I only wrote a brute-force thingy this morning, so I didn’t even think about doing anything related to polynomials or `double`. 😅 Even part 2 only took 55 ms. But for DOS, this wasn’t an option anyway, so I did the proper math while waiting for something at work. 🤣)
It’s still a bit surprising to me. Usually, AoC doesn’t require such tricks and most things fit neatly into 32 bits. Maybe there’s a better solution after all. 🤔 I might have a look at reddit.

@movq it shouldn't need a full bignum implementation right? Just some left and right shifts for the sq/sqrt and carry for the addition right?

Today’s AoC puzzle is a very simple problem on modern machines, but quite tricky for me: It involves a number that doesn’t fit into 32 bits. 🤔 I wonder if/how I can manage to port this beast to DOS. (I once wrote a “big int” library myself, but that was *ages* ago and I hardly remember it anymore.)

@xuu I see, interesting. 🤔 Now I’m curious if I could optimize my brute-force solution as well. 😅 (I wrote a “proper” solution in the meantime after watching a visualization by someone else.)

The word forms is part two. In this one you want to find the first digit and last digit. Think searching '1' - '9'

All brute force.
Its the latest ryzen 7 chipset for laptop/mini form factor.
I am very surprised about the times others are getting. I guess that's the difference between interpreted and compiled showing.

Last night it got much warmer (~6°C) than it was on the day itself (below freezing). That usually never happens. The snow melted and little avalanches came crashing down the roof. All the bangs scared the hell out of me last night.

@prologic Doing AoC competitively is super hard. I don’t enjoy this at all. I just *happened* to be quick these first few days. 😅
I rather set my own goals. Like the DOS thing this year. That is a lot of fun. 😊 (I just have to remember not to check the leaderboards. 🤣)

@xuu I ask myself that question every year. 🤣
To be fair, the first part wasn’t really that difficult. If you have *A LOT* of experience with these kind of problems/puzzles and if you have a proper framework, I imagine it’s doable. (I, on the other hand, spent about 40 minutes just writing my C code to parse the input.)
Some of these people record themselves and then post it on YouTube. It’s pretty crazy to watch. 🥴
The second part of the puzzle, was/is pretty hard, though. At least for me, because I haven’t found “the trick” yet. I’m currently trying to brute-force it while having breakfast. 😅 (But given that it took ~8 minutes for the first person to get both stars, maybe they brute-forced it as well. With a faster machine and multithreading, ~8 minutes sounds about right. Brute-force is rarely the answer in AoC, though.)

@eapl.me I have many fond memories of Turbo pascal and Turbo C(++). They really did have a great help system. And debug tools! Its rare for language docs to be as approachable. QBasic was great. As was PHP docs when I first came into web.

My #AdventOfCode2023 has been calculating statistics for manufacturing 😆
Today was processing a list of states (e.g. A from 6:40 to 7:25, B from 7:25 to 8:15) and getting what happened hourly from 6am to the next 24 hours.
Put timezones into the equation for more fun.
And finally explain all that to the Jr.
