Implement a movie rental system with the following operations: 1) search(movie_id): Returns the 5 cheapest channel IDs for the specified unrented movie. 2) rent(movie_id, channel_id): Marks the movie as rented from the specified channel, so it will no longer appear in future search results for that movie. The system should handle a vector of vectors containing movie ID, channel ID, and price information.
