Day 1 wasn't so bad, depending on approach. People got tripped up hard with replacing strings because of the old "twone." If you didn't happen to do string replacements it wasn't so bad.
Day 3 absolutely wrecked me though - and my overall rank was still pretty significantly better than it had been on days 1 and 2.
- On the flip side, twone absolutely ruined my life. Worst part was that I was looking at it and thinking "yes I handled that edge case and am only taking the first number, why's it not working"
  Everything else has been a breeze. I'm using typescript and it's been chill.
- If you didn’t happen to do string replacements it wasn’t so bad.
  Yeah. I was using regex to find the numbers as a quick implementation before realizing that floor. Just switched it to use a positive lookahead to solve that issue.
  Day 3 was one of those challenges that if you thought of a good method quickly it wasn't too bad. Ended up compiling strings and using regex again. Worked really well actually.
- Not only replacing didn't work. I did it as a regex, but Rusts regex crate only supports non-overlapping matches.
  
  Python's re also only supports non-overlapping matches and only one direction, so what I did was
  
  There are probably more elegant ways, but I couldn't come up with anything as simple as this.
  
  Oh, nice.
  I just replaced those compounded words with their non-overlapping counterparts.
  
  Oh, cool, I did pretty much the same thing, just finding the words manually instead (didn’t want to use any external libraries, so I just wrote a function to search for me. Haskell doesn’t have much for OOT B functionality).
