Retention Rating Analysis

Problem: Retention Rating Analysis Given: users(user_id, city) rides(ride_id, ride_date, ride_rating, user_id) For each user with rides, order the distinct calendar months in which the user had at least one ride. These are the user's 1st, 2nd, 3rd, ... active months; inactive calendar months are skipped. For each city, compute: the average rating across all rides in users' first active months; the average rating across all rides in users' third active months. Do not compute an average of per-user averages. Return city, first_active_month_avg_rating, and third_active_month_avg_rating.
