I have no idea what made me decide to participate in AoC this year (maybe the 12 days seemed more do-able with Christmas and end-of-year responsibilities). In any case, I've really had to break the rust off of my Alteryx skills after moving into a product owner role 😅 It took me way longer than it should have to work out the "pass zero" critieria!

Happy to see so many solutions here.

It is very simple. We just have to add/subtract the value as per the given increment/decrement. When the absolute value is divisible by 100, it's passed.

Mod(ABS([current]),100)=0​
