Performant solution to 2024 day 11.
...
We notice that we're repeating calculations at each step, so use a
map to ensure we do each stone ID once per step.
2024-12-11 09:16:57 +00:00

Not happy that mutable state is being used. But this seems to be the
simplest way, and is efficient.

Simplify the code for 2024 day 7
...
Simplify may be in the eye of the beholder here.
This reduces code duplication, as both parts are effectively the same.
Part 2 just has an extra operation that can be carried out.

Do not use a set to record blocks in 2406.ml
...
Instead of using a set of locations to store the blocks in day2406.ml
return to using a string.
Sets have an O(lg n) lookup time in number of blocks.
Instead we use a single string which contains the whole map, which means
we can do O(1) lookup on a block. This significantly improves
performance.

Move IntPair and PosSet into Aoc library.
...
These are obviously generic enough and useful for the future that they
can be moved to a shared library.

Reimplement 2024 day 6 to use a set.

This seems "better" from a functional perspective. However, it runs
substantially slower for part 2.
