Create a priority queue, adapting a default-constructed container of the (template parameter) type CONTAINER, and inserting into the container a sequence of value_type elements that starts at the specified first and ends immediately before the specified last. Use a default-constructed comparator of the (template parameter) type COMPARATOR to order elements in the priority queue.
