Day 25

	Part 1	Part 2	Total
Time	17:58	44:36	1:02:34

It's been a blast! This is my first time ever completing all the puzzles of an Advent of Code year, and it feels great! I grinded on 12/24 before midnight to get all the puzzles I was behind on (due to exams and Christmas activities). Unfortunately, I was not able to complete Day 24 Part 2 in time, so my 50th star was locked out. After completing Day 25 Part 1, I decided to stay up and work on Day 24 Part 2 (which honestly was just waiting for my silly code to finish running 30 minutes later).

I was 2077th to complete Day 25 Part 2 and hence, 2077th to complete all of Advent of Code 2022! (That's 1=2=02th in SNAFU.)

It's been a wild ride, and a whole lot of fun;
Talking with elephants, monkeys, and elves.
We learned a lot and improved ourselves.
Goodnight, and Merry Christmas everyone!
