badvent_of_code_21's Introduction

badvent_of_code_21

Jerry's really horrendous at writing clean code. Or code at all.

more details

I wrote most of this project first in Java first for speed, and then rewrote it in Python (and potentially other languages to learn). Day 12 onwards was written in Python.

My initial speed code has not been refactored in any way - it is left as-is.

My Python code makes use of numpy very heavily.

Notes:

Day 1 started late
Day 7 had a submission issue because servers were overloaded
Day 19 was too difficult, did not solve within 24hrs.
Day 22 part 2 was a brute force. Suffice to say that it's the most lopsided finish I've seen in AoC for a while.
Day 23 was manually solved because I forgot how to code entirely.
Day 24 was also manually solved, cuz coding difficult.
Day 25 was difficult because I had to get back into the swing of things coding and forgot how to code again.
