Good luck :slight_smile:
FYI one of the features of Advent of Code is that we all get given different inputs so our answers will be different.
The examples are all the same but each of us gets different inputs for us to solve

Took a while to run but managed Part 1

Part 2 looks like it's going to need a completely different approach!
And while looking at Part 2 I realised I could do Part 1 much faster so I've added that version as well

Can’t read your link. :slightly_frowning_face:

Part 1

Part 2 (added)

Calculate the difference between the expanded vs. original universe, multiply by 999,999.

Works at my end

Works now, for me too.

Glitch in the matrix then :slight_smile:
