2021 Day 25

— Day 25: Sea Cucumber —

The floor is just there, but it is covered in sea cucumbers.

Find somewhere safe to land your submarine. What is the first step on which no sea cucumbers move?

library(tidyverse)

my_file <- here::here("2021", "data-2021-25.txt")
x <- readLines(my_file)

Loop a little to make sure we are moving properly, and then let the cucumbers move.

# here's another R cell for good luck
