(I created the topic, because I did not find any for this puzzle.)
I just want to highlight that this puzzle has the best, most helpful set of test cases ever on CG! Without these inline hints, it would have been much less fun…
Congrats and big , also for the puzzle idea!
I always knew that WebChat HAS TO have some meaning… (at least when I am not trolling there)
PS: Part 2 of this puzzle seems to take a bit too long in the making, or where is it?
