I just completed "Binary Boarding", this one was pretty simple (except there's probably a way easier way to do part 2 lol) https://susepaste.org/a3c872f9 #AdventOfCode https://adventofcode.com/2020/day/5
@trwnh what's expected sums?

@noiob
because they're all sequential but exactly one number is missing: the expected sum is the sum of the range from min to max. if you take that expected sum and subtract the actual sum, you get the one missing number.

@trwnh oh! yeah that's way smarter
@noiob bit of a tossup really. you could use expected sums, but detecting a delta of 2 is perfectly fine
