The changes
The challenge has been shortened to 12 days, and the global leaderboard has been removed. This last change will probably displease some AI bros.
Objectives
I will try to solve all the days, with solving times inferior to 6 hours. The puzzles are unlocked at 6 AM in my country, so I will have to submit solutions before noon.
I will also try to produce efficient code, with a combined execution time inferior to 1 second.
Tools
This year, I will use Scala 3. I have already solved 5 Advent of Code challenges with this language (2015 to 2017, 2023 and 2024). My text editor will be Vim 9.1.
Repository
My code will be posted on my Redmine forge, and commented on this blog.
