The task
In C++, to use a user-defined type as a key in `std::unordered_set` or `std::unordered_map`, you need to provide both an equality operator and a hash function. While you can pass a custom hash functor as a template argument (e.g., `std::unordered_set<X, MyHash>`), it is more convenient and idiomatic to specialize…
