Mini-Project: The Ten Pattern Toolkit

Build one reusable function for each of the ten patterns, all operating on a list of member records (name, city, hours, joined): count_by_city, total_hours, find_member, filter_veterans, names_only, fewest_hours, sort_by_hours, unique_cities, is_symmetric_name, and find_year_binary (on a sorted list of years). Every function must RETURN, handle an empty list safely, and be called at the bottom on a dataset of at least eight members. Both languages.
