Advent of Code 2022

Commentry from Reddit

Post by u/paul_sb76: [2022] How would you rate the difficulty of this year's puzzles?

Trivial: 1, 2, 4, 6 Easy: 3, 5, 8, 10, 12, 18, 20, 25 Medium: 7, 9, 11, 13, 14, 15, 21, 23, 24 Hard: 16, 17, 19, 22

I'll use this as the order to finish the rest of the puzzles over time.

Instructions

./day06 -part b [-file <filename>] [-debug]

Day 7 - No Space Left On Device

• Day 7

Needs tidied up. Part b doesn't give the answer directly. You need to pick from a list and work out what's the lowest value.

./day07 -part a [-file <filename>] [-debug]
./day07 -part b [-file <filename>] [-debug]

Day 8 - Treetop Tree House

Day 14 - Regolith Reservoir

• Day 14

Note for part B: it will print out the complete finished cave system which is fun to look at!

./day14 -part a [-file <filename>] [-debug]

Day 20 - Grove Positioning System

• Day 20

First time using container/ring. Wish it had a few more features, might have to write something which has the extras I needed. Part b added optimisation from dhruvmanila. Changed my solution from taking several hours to under a second!

./day20 -part a [-file <filename>] [-debug]
./day20 -part b [-file <filename>] [-debug]

Day 21 - Monkey Math

• Day 21

Need to revisit Part B. I've got the answer so I'm carrying on with other puzzles, but this code is utter crap and needs manual help to get the answer. To make it work, change humnShouts in calcMonkeySpeachPartB(). Set it to 1 to start with, and set changeSteps to a big number (say 1000000000). When the code stops, take the "humn shouts" number output 3 STEPS ABOVE where it stops. Use this number to replace humnShouts in the code, reduce the size of changeSteps, then run again. Repeat until you get the result "humn needs to shout: " and is the result you want.

./day21 -part a [-file <filename>] [-debug]
./day21 -part b [-file <filename>] [-debug]

Day 22 -

Day 23 -

Day 24 -

Day 25 - Full of Hot Air

• Day 25

There's no part B for Day 25. "Just" need to complete all the other days and you're given the last star.

./day25 -part a [-file <filename>] [-debug]
