-🎄- 2021 Day 15 Solutions -🎄-
Python solution. Part 1 runs in no time at all. Part 2 takes about 1.2 s which, I think, is because I am creating the entire 500x500 grid at the beginning. I suspect that I could speed it up considerably by only creating a grid in a direction when I get there, maybe create the next tile to the right and down when I get to a tile. A tile update function would probably not be too difficult as each cost would be an (x,y) multiple of the cost's base (x,y). I'm going to attempt to bring this to below 1s. :D

My solution in Python. Part 1 was pretty easy to do with sets. For Part 2, I just printed to console and put in the letters. :D

-🎄- 2021 Day 11 Solutions -🎄-
Surprised at the pretty small input file size :D but pretty easy Python solution using dicts, lists, and sets. Python comprehensions just make life so much easier.

-🎄- 2021 Day 9 Solutions -🎄-
Finally managed to solve Part 02 in Python. I was stuck because I could not figure out a way to go through all the points around a low point till I got to a 9. Then yesterday I say u/skarlso's post about Red Blob games and the various pathing algorithms, and the breadth-first-search example just unblocked the whole solution for me. :)

-🎄- 2021 Day 6 Solutions -🎄-
Python solution that takes about a second for part 2. The logic is the same for both parts, just changed the number of days it runs for.

Bless Python's sets! Makes checking for membership such a breeze!

-🎄- 2021 Day 3 Solutions -🎄-
Pretty easy with Python. Some list comprehension, some count, some join, some int and it's done. Could be more efficient, of course. 😁

-🎄- 2021 Day 2 Solutions -🎄-
Simple Python-based solution yet again.

-🎄- 2021 Day 17 Solutions -🎄-
Python day 17 solution (GitHub). Not the fewest lines of code, but used dataclasses and modular functions to try improve readability -- I got very confused with keeping track of indices of velocities vs coordinates in other people's posted solutions. I find dataclasses in Python can be a great way to be descriptive about the quantities you are iterating

Python day 15 solution (GitHub) using Networkx for graph algorithm and Numpy for building the bigger grid. Solutions to other days available in this repo

-🎄- 2021 Day 14 Solutions -🎄-
Python day 14 solution (GitHub). Tried splitting out the logic into individual functions to aid readability.

-🎄- 2021 Day 6 Solutions -🎄-
Python solution using deque (GitHub). Much faster than my first attempt, lol

Python day 5 solutions using Bresenham's algorithm (Github)
-
-🎄- 2021 Day 4 Solutions -🎄-
Python solution day 4 OOP (GitHub). Probably not the fewest lines of code but uses dataclasses and OOP to manage the states of each bingo card
