I just completed "Custom Customs" - Day 6 - Advent of Code 2020 #AdventOfCode https://adventofcode.com/2020/day/6 in #JuliaLang.
Every day, while implementing Part 2, I end up with a more elegant neater way of doing Part 1. Never occurs to me while doing Part 1 itself - probably because I come up with an idea while reading the question and rush to implement it, not stopping to think of other ways of doing it .
