There's still a bit of time — shall we try to optimally rewrite the ROC-AUC solution (using sorting and ranks in O(n log n))?

Recommendations for blocks on the main page of an online cinema Write a plan to solve a product task from reviewing required data to training, testing, and deploying a model (or, if possible, without ML - then without a model). The online cinema has a main page. It consists of different blocks. There is a catalog of blocks. Blocks can contain different amounts of content. There is a ready-made movie recommender, i.e., a catalog of movies ordered by relevance. Design a personalized block recommender and its application algorithm, which satisfies the business rule - show one content on the main page once.
