Implement Game Metadata Lookups

You are given a list of game metadata records. Build an in-memory representation that can store each game's name, release date, platforms, genre, publisher, optional country, and relevant Discord servers. Then implement lookup functions over the data. Example input: ```python games = [ { "name": "Cyber Quest", "release_date": "2025-01-01", "platform": ["playstation", "xbox"], "genre": "RPG", "publisher": "GameStudio A" }, { "name": "Battle Arena", "release_date": "2024-11-15", "platform": ["pc"], "genre": "Action", "publisher": "GameStudio B" }, { "name": "Sky Adventure", "release_date": "2025-02-10", "platform": ["playstation"], "genre": "Adventure", "publisher": "GameStudio A" }, { "name": "Mystery World", "release_date": "2023-07-20", "platform": ["xbox", "pc"], "genre": "Puzzle", "publisher": "GameStudio C" }, { "name": "Speed Racer", "release_date": "2025-03-05", "platform": ["pc", "playstation"], "genre": "Racing", "publisher": "GameStudio B" } ] ``` Implement the following functions: ```python def get_genre(input_game): """Given a game name, return the genre of that game. Return None if not found.""" return None def get_games(input_genre): """Given a genre, return a list of game names with that genre.""" result = [] return result def get_most_available_games(games): """Return all game names that are available on the largest number of unique platforms.""" result = [] return result def get_available_games(number_of_platform): """Return all game names that are available on exactly number_of_platform unique platforms.""" result = [] return result ``` Requirements: - Treat game-name and genre lookups as case-insensitive. - Count unique platforms for each game. - If multiple games tie for the largest number of platforms, return all of them. - Preserve the original game names in returned results.
