This is it. The last puzzle of the event. We’ve almost made it through. The only thing that stands between us, and the sleigh keys are two herds of sea cucumbers. Cucumbers are constantly in the move, and our task is to simulate their behavior.
Unfortunately, I’ve decided not to solve this task. It does require reverse-engineering the given code, and I’m just not motivated enough to do that. So yet another task that needs to be done by hand is just too much for me. Sure today’s task is interesting, I’m just too exhausted to do it.
And they did it again. Today’s task is yet again “try this easy part, that can be solved by brute force. Yes, correct… now suffer from all this extra data you need to process” type of task. Our task is to move every Amphipod into their room:
Today we need to reboot the reactor. Unfortunately, the reactor is made out of cuboids that can intersect in 3D space. First part requires us to figure out which cubes are on or off, but only for the range of -50 to 50 for each coordinate.
As it seems, when there are neither any problems to solve outside of the submarine nor inside of it, the computer still wants to give us some trouble! This time, though it is just a mere desire to play a game with us.
With the scanners fully deployed (totally, yeah, totally), we now can compute the map of the trench. But when we get the image from the scanners, it looks like a random noise (I wonder why, perhaps because of the extremely convoluted positioning in the previous task?
Unfortunately, I wasn’t able to solve this task. I seriously couldn’t understand what I even need to do with all these coordinates. Maybe I’ll solve it later, though I highly doubt that I’ll come back to any missed day or previous events for that matter.
This weekend is quite different from the last one! Tasks are much harder this time, and I’m also out of the town without my laptop. So I’m writing this on my phone!1 I’m doing it in Emacs, installed inside Termux, which thankfully has a lot of packages, that allow me to continue working even without a laptop.
Today we need to send the probe into the ocean trench. To do that we need to fire the probe with certain x and y velocities, which are integers. For the first part, we need to find such velocity that the probe reaches maximum y position while still reaching the trench.
We’ve finally left the caves! This is such a relief, no more walls full of Chitons, or volcanic activity. And since we’re out of the caves, we’re able to receive a transmission to our submarine! The transmission is encoded with the Buoyancy Interchange Transmission System (BITS) and is represented in hexadecimal.
