Day 5 - If You Give A Seed A Fertilizer

• Day 5

Part b is Sloooooow but I decided I don't care :-)

./day05 -part a -file input
./day05 -part b -file input

Day 6 - Wait For It

Expected to change to an equation to solve part 2 but my naive solution ran in under 0.1 sec so I didn't bother

• Day 6

./day06 -part a -file input
./day06 -part b -file input

Day 7 - Camel Cards

Long winded code. Could collapse part b into part a easily and reduce the amount of code but I'm behind on AoC so not going to do it.

• Day 7

./day07 -part a -file input
./day07 -part b -file input

Day 8 - Haunted Wasteland

LCM needed to speed up part 2

• Day 8

./day08 -part a -file input
./day08 -part b -file input

Day 9 - Mirage Maintenance

I don't understand how I made part 2 work, but it does so I'm done.

• Day 9

./day09 -part a -file input
./day09 -part b -file input

Day 11 - Cosmic Expansion

Had to rewrite once I saw part 2 and realised I didn't need to map out the expanded universe

• Day 11

./day11 -part a -file input
./day11 -part b -file input
