# Advent Of Code '2023

My [Advent of Code](https://adventofcode.com) adventures.


Estonian private leaderboard (by petskratt) is here: https://adventofcode.com/2023/leaderboard/private/view/652748.

## Diary

* `Day 01` **Trebuchet?!**: The part #2 had quite a clever trap in it, making initial _"common sense"_ 😁 left-to-right

  approach fail.

* `Day 02` **Cube Conundrum**: Very simple once you understand the task. I am a slow reader, though.

* `Day 03` **Gear ratios**: I absolutely HATE _any tasks_ that involve keeping track of _**position indices**_! 🤮

  The parts adjacency checking is too complex, because I expected the parts can be of any length - this did not happen.

* `Day 04` **Scratchcards**: #1 was super simple; #2 was hard to visualize - a straightforward rules-based simulation 🤖

  did the trick!

* `Day 05` **If You Give A Seed A Fertilizer**:

  1. Computing is easy, but...

  2. Idea of super-positioning of individual transformation steps was easy, but implementation required mental clarity I

     am usually short of! 🤯

* `Day 06` **Wait For It**: Just solving a square equation w discrete values. I wasted an insane amount of time

  because of using 'analogue' approach instead of 'digital' one (starting at line 19)... w/o taking some time to think

  it over. 🫠

* `Day 07` **Camel Cards**: Puzzle #2 really required a keen eye 🤤 when reading the description.

* `Day 08` **Haunted Wasteland**: This was just ingenious - it is _**so important**_ to follow task description details!

* `Day 09` **Mirage Maintenance**: Easy. 🌴🌴🌴

* `Day 11` **Cosmic Expansion**: Unexpectedly simple. But as usual, I lost quite some time because of appallingly stupid index error. 🫠

  At stage #1 I implemented the gaps quite inefficiently, thinking that this weirdness might pay off

  at stage #2 (maybe new galaxies should be generated or something)... it didn't!

Up there, prefix _'M'_ stands for _main_ and _'D'_ for _demo data_.


When some results from step #1 are re-used, then step #2 can be quicker.
