I just completed all 25 days of Advent of Code 2024! #AdventOfCode adventofcode.com
Well after struggling a couple of hours with day 24, day 25 was pretty easy.

I just completed "Crossed Wires" - Day 24 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/24
This task was really difficult for me. ChatGPT had no chance and I only solved part 2 semi-automatically.

I just completed "Monkey Market" - Day 22 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/22
I convinced ChatGPT to introduce a bug in its code. It's annoying, but maybe a consequence of its system prompt to be helpful and polite. The rest was easy (compared to yesterday).

When using ChatGPT as a pair-programmer, something really annoys me: My brain gets lazy, so I tend to think less about the problems. That is fine if ChatGPT provides the perfect solution. In all other cases, solving the problem actually gets harder.

I just completed "Keypad Conundrum" - Day 21 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/21
ChatGPT had no chance of solving it. As always it started by suggesting a breadth-first search. At the end I had to implement my own solution, which ran - thanks to caching - blazing fast.

I agree, but you can't earn money with "look at my fancy autocompletion algorithm". 😉

ChatGPTs love for breadth-first search strikes again. I don't know why, but it always suggests this algorithm although it is most of the time the wrong approach. It's annoying.

I might have improved my ChatGPT skills, because this was easy to solve. Or it is just luck. We will see tomorrow.

After struggling the last days, this was easy to solve. I trusted my intuition and all I learned from the past (human intelligence ftw). ChatGPT was very valuable in implementing the A* search.

ChatGPT likes brute force approaches. After realizing that this cannot be done using brute force, it was actually very valuable when understanding the program step by step.

Again, ChatGPT failed to solve part two on its own. I had to guide it step by step. My learning: Provide ChatGPT clear and precise commands, do short iterations and always check the code.
