Advent of Code 2019 wrapup

I enjoyed this year’s edition more than last year’s.

It was a combination of being slightly easier, and having a better attitude to it coming in. In 2018, I was aiming for as good a result as I had in 2016, which was 49 stars out of 50. This left very little margin for bailing out of tough problems, and led to increased frustration when I didn’t have the time required to solve a problem within 24 hours.

I was thinking of not participating, but as time drew near, I got inspired, and even solved a couple of left-over problems from last year in preparation.

This year I gave myself more leeway for simply bailing on problems that didn’t seem fun. This turned out to be day 21. I also gave up on day 6, which was probably a mistake, and part 2 of day 22.

I also felt that this year was easier than 2018. In part, this was because of nearly half of the problems being intcode problems, where we first had to write an interpreter for a specific machine code, and then apply that interpreter to various fun follow-up questions, like playing Breakout or Adventure.

Then I had a lot of support from the dedicated IRC channel from I’d like to thank regulars jjuran, wink, gthm and tumdum for encouragement and friendly competition.

I still have a number of stars to get, but unlike last year, I’m looking forward to solving those problems.
