Ah need to catch up. Still on day 8. I thought the switch to 12 days from 25 days this time will be easier, but a linear interpolation applies here also - it gets harder in the middle as always.

Every assumption about Part 2 was wrong I think. If the operators row had padding whitespaces then we could simply do a reverse traversal picking the numbers from each row, combining them, and operating on them as soon as we encounter an operator.

Tried `list.each { toList() }.flatten().distinct().count()` but got OOM error 😆 Thanks for the idea of merging the ranges first.

Great so far, but stuck at D03P02
