Solver for The Password Game, specifically the section "The elements in your password must have atomic numbers that add up to 200"

password_game_elements_solver.py

# This is a solver for The Password Game: https://neal.fun/password-game/,
# Specifically the section "The elements in your password must have atomic numbers that add up to 200"

# It's written as a Flask app because I was sharing it with my friends that were also playing.
# However you can just use the function `get_required_elements_for_password_game(password)`
# to do it locally

# Got ChatGPT to write the element list for me
