It's not a good sign that this meme appeared on day 1 already...
It's great! I've had community members point me in the right direction after already "solving" it incorrectly. It really makes you think about it. You have to expand your test cases and really come up with a better solution.
Not to say it isn't difficult especially if you expect the problem to be described perfectly accurately.
I don't need a perfect instruction set, but dang if the examples couldn't be better sometimes. Like
sixteenwas in there to show it only counted for 6, but nothing with overlapping text.
I've solved part 2 multiple times now, but small intricacies keep popping up every time.
I'm stuck on one of these intricacies now! I saw some of the ideas on how other people did it but i honestly have no clue what i did wrong. Got any tricky examples to share?
I was having a bitch of a time with day 1's part 2 until someone pointed out that sometimes two numbers share a first/last letter (eightwo).
Those overlapping spelled out numbers were rough
It was for sure to catch people that were taking the easy route and using a replace. I had to rework my solution to get the start positions for the matches. That method made both parts easy to get together.
it seemed pretty straightforward in python - just make a list of text->number, use that to make the regex, then use it again to convert back to numbers
its relatively fine, just harder than past day 1s and has cases that trip people up
I managed the overlap logic just fine (if in a clumsy way), but spent over an hour trying to debug my crappy parser-combinator code when the issue all along was a mis-spelling in my lookup table.
