Can someone ELI5 Part 2 for me, please? 🤯

[Dan Fingal-Surma]

OK actually it’s like this:

[Dan Fingal-Surma]

Think of every gate as having a output connection to a wire

[Dan Fingal-Surma]

For some pair of gates (four times), you need to swap the wire the gate output is connected to (this wire may itself be connected as an input to other gates, or it may be a zOut wire)

[Jakub Gwóźdź]

is it possible that there is multiple solutions? I found one but server says it's wrong answer...

[bj0]

i don't think so

[Jakub Gwóźdź]

Well yeah it’s possible. My solution worked only for the example x0..x45 and y0..y45, not general x and y 😁

[Dan Fingal-Surma]

there is exactly one solution

[Petr Sýkora]

Got my result for part 2 in 24 minutes of runtime, forgot to return/log/write it, priceless 😄
