My initial solution required subtracting off 3, but I cleaned it up afterwards:

The Advent Of Code season has arrived again this year.

I joined this event as anonymous user #1105310 last year, but this year I joined by GitHub account that is the same as Community account name.

Tried solving part 2 without using the same Multi-Row Formula approach I took in part 1 - not a bad initial puzzle.

This is my first time taking part in Advent of Code - and also first exercise undertaken.

Looking forward to the next couple of days as we get to some of the tougher ones

 

I'm surprised that they didn't ask you to bring the data down via an API...

Late for the festival exercise, but here I am 😉

Noticed some order change after multi-row formula, so had to use sorting. Also, learnt a neat solution by reading the thread.
