Personnal Feedback

Day 01

As usual, day 1 is pretty simple, so I took some time to just write some script to autogenerate everything I need to start working.

I do have a small complain about that day: part 2 is a bit unclear on the “oneight” problem (basically: this is “18” and not “1ight”)

Day 02

Simple day, the hardest part was parsing the input.

Well the actual hardest part was importing and learning how to use the regex module but whatever <:)

Day 03

Repeat after me: manipulating 2D grids in Haskell is not fun.

I spent like 40 minutes on parsing the input… 😿

Day 04

Was fun 😸

Day 05

Challenging enough to make me take out a pen and paper, simple enough to make me solve it

Day 06

I am now convinced that odd days are hard and even days are easy.

This is just simple maths!

Day 07

Not too hard, so I decided to have fun with Instances!

Day 08

I hated that I took a wild guess for part 2

Day 09

This was probably the easiest one so far

Day 10

I overcomplicated things once again

Day 11

Well that was easy :)

Day 12

What do you do when your bruteforce solution is too inefficient? YOU DO MEMOIZATION! :D

Day 13

Easy peasy lemon squeezie

Day 14

Not a hard day, but I’m a bit ill and I ended up going from an awful solution first before reworking everything.

Day 15

THAT’S IT???

Day 16

Spent 20 minutes debugging. Didn’t notice I swapped north and south somewhere.

Day 17

Please lord have mercy on my sould and stop giving me puzzles involving 2D grids.

Also, I was definitely not recoding an A* or a Dijkstra on the stop. No can do.

Day 18

This is simply computing an area. Nothing more!

Day 19

It took me a while to understand part 2 (thank you Adam for your explanation)

Day 20

I am once again asking you to analyse the input and make random assumptions.

Day 21

Stop making me analyse the input :)

Day 22

Problems in 3 dimensions usually scare me. But it turns out this one barely makes use of its third dimension, so all is well :D

Day 23

Now this is the AoC I like, where analysing the input gives me hint at what a more optimised solution could be, without making my solution input-specific!

Day 24

My first time using a SAT solver!

Day 25

Didn’t really solve it with code lol
