/g/ has a tradition of making ‘big boy’ inputs, much bigger data inputs for the various challenges, as a sort of voluntary filter that splits the O(N^Compsci graduate) from the real hackers who can google quicksort, and the occasional madman who considers letting O(N^3) code run for 5 hours an acceptable workflow.
These inputs will test your implemention to its limit. Either that, or your patience and the gaming laptop mom bought you.

Some of these inputs have different rules from the default AOC inputs; these ones have the extra rules quoted. Some of the inputs also have the ‘answer’ hidden in a details tag beneath them, so you can check your result without spoiling yourself.

Big Boy: Day 1
The target sum is 99920044 rather than 2020.
Also, there are apparently multiple valid solutions to part 2 for the bigboy, as it was made with part1 in mind…
Correction: anons say this dataset only has one valid solution!
Day One Spoiler: The number triplet
20940485, 38299301, 40680258 are the three numbers that sum to 99920044.

Big Boy: Day 4

I decided to make a big boy input for anyone who’s interested

My times:
0.8s for part 2 only, using >>79033783
1.2s for both parts, using the C++ solution in >>79032211

It even triggered a bug in my C++ solution that I didn’t discover earlier.
Day Four Spoiler: Numbers of valid passports
