Description:
Advent of Code 2021 Day 2, Solved in RnnI solved the first two days of AOC 2021 before making these videos. Although you see me programming the solution from scratch, I did pre-download the data and I have read the question already, so I spend less time on the text than I might otherwise.nnnSolution approach: dplyr. Read data as delimited file into tibble; treat each operation as atomic and calculate how coordinates changed, treat aggregate playback as a summarize operation. For part 2, use cumu
