I've completed Part One of "Step Counter" - Day 21 - Advent of Code 2023 #AdventOfCode https://adventofcode.com/2023/day/21

Done with #php

Part 1 done, Part 2, no more time to improve it.
Have a way to calculate approximation, but need to be more accurate. Probably close to something (and "image" appear in personal input maybe be a clue 🙂)

Some objects for clean code: https://github.com/velkuns/adventofcode-2023/tree/main/src/Day20

Part 1 was easy with clear logic in mind, no bug.
Part 2 ... still running (it tooks ~ 55s for 1million times), so I don't know when it will finish, but probably in long time 😅
Maybe the response tomorrow morning 😄
But it was fun to code !

I've completed Part One of "Aplenty" - Day 19 - Advent of Code 2023 #AdventOfCode https://adventofcode.com/2023/day/19

Done in #php

Code: https://github.com/velkuns/adventofcode-2023/blob/main/src/Day/PuzzleDay19.php

Just only the part 1 today. I don't really like this kind of part 2 with optimised range calculation, so just skip it and have some rest for remaining time :D

I just completed "Lavaduct Lagoon" - Day 18 - Advent of Code 2023 #AdventOfCode https://adventofcode.com/2023/day/18

done with #php

Part 1: hard to try appropriate formula & fix the code, part 2 will provide the exact result without any fix or change.

Code here: https://github.com/velkuns/adventofcode-2023/blob/main/src/Day/PuzzleDay18.php
Also re-use an enum from Day 10: https://github.com/velkuns/adventofcode-2023/blob/main/src/Enum/PathDirection.php

Pfiou, long fight with my code and condition, after learning usage of Priority Queue for this puzzle

I just completed "Lens Library" - Day 15 - Advent of Code 2023 #AdventOfCode https://adventofcode.com/2023/day/15

Done in #php

Pretty simple today.
Probably can do it with less lines, but it will be more difficult to read & understand the code.

I just completed "Parabolic Reflector Dish" - Day 14 - Advent of Code 2023 #AdventOfCode https://adventofcode.com/2023/day/14

Done with #php

Not so complicated today. Once again, my Matrix class was very helpful.

And final try was false due to miss read the number of cycle to reach (1 million instead of 1 billion 😅)
Fun fact: brute force will take ~100 year to achieve with my current code 😆

Pfiou, lots of stupid bugs in my code for part 2. But finally done after 4 tries.
My Matrix class is clearly the best class for this kind of puzzle game, that help me a lot.
Probably can optimise the part for try to fixing smudge, but it is quite reasonnable (and also improve naming) 😅

I've completed Part One of "Hot Springs" - Day 12 - Advent of Code 2023 #AdventOfCode https://adventofcode.com/2023/day/12

Done with #php (only part 1 for now)

Code is here: https://github.com/velkuns/adventofcode-2023/blob/main/src/Day/PuzzleDay12.php

Pretty simple solution (not really optimised), but obviously not usable for part 2.

Have an idea for part 2, more reasonable, but need some more time to implement it. But keep pretty same logic.

https://github.com/velkuns/adventofcode-2023/blob/main/src/Service/Universe.php (extended Matrix)

Quite simple today, but a little bit challenging on part 2

The time to process for part 1 can be around 180ms (2 times less) by using real expanse of the matrix
