Part 1 is fine. part 2 gives wrong answer. I've had no time to work on this between moving, chores and errands associated with it, and debilitating headaches I get sometimes. I found all of the operations that seem to be singletons by removing ids from contention, but it yields the wrong answer. So either I'm doing that wrong and have the wrong instructions or I'm executing one wrong. Blah.

Yeah, it can be frustrating. But don't sweat it, the point is to have fun, and if it isn't fun for a while, just skip it until you have the time and energy. These puzzles will be here for you to enjoy later as well! 

True. I don't need more stress on myself. If I can't write it up I just can't.

right after I sent that last message I had to run some errands and just got back. I figured it out in a background thread while I was out shopping - my regex was wrong! 2 seconds of fixing solved it! :slightly_smiling_face:
