The submarine has been making some odd creaking noises, so you ask it to produce a diagnostic report just in case.

Just between you and me, what are the odds I end up in a watery grave?

Times for today: 8:38, 29:57. I wasn’t rushing, I spent some time reading in the middle. My code was embarrassing, so I’m not going to post it here. Suffice it to say, it was a transpose text and count stuff kind of problem. Tomorrow I want to try screen recording myself, since it’s the weekend and I’ll have more time.

I made a little visualization of the submarines progress so far. I didn’t mean to give myself vertigo, but here we are. I had to mess with units and stuff to get this to look nice; either the scale is tiny or santa has discovered an ocean trench multiple times deeper than marianna.

red line is the ocean floor, day 1's input, yellow is the path from day 2 part 2. matplotlib.
