Advent of Code 2023

Reflections

• Day 1: Learned about lookahead assertions in REGEX
  • (?=...) positive lookahead - matches if ... matches next, but doesn't consume any of the string
• Day 5: Python doesn't do tail recursion optimization...???
• Day 8: Learned about itertools.cycle but also should've thought to verify if cycle length was constant (reason why LCM works)
• Day 9: Resist the urge to curve fit everything Jen...
• Day 10: Learned about Pick's theorem and the Shoelace theorem (also Python supports switch statements now! yay)
