24.6.5 Class template priority_­queue [priority.queue]

24.6.5.2 Constructors [priqueue.cons]

priority_queue(const Compare& x, const Container& y); priority_queue(const Compare& x, Container&& y);
Preconditions: x defines a strict weak ordering ([alg.sorting]).
Effects: Initializes comp with x and c with y (copy constructing or move constructing as appropriate); calls make_­heap(c.begin(), c.end(), comp).
template<class InputIterator> priority_queue(InputIterator first, InputIterator last, const Compare& x = Compare());
Preconditions: x defines a strict weak ordering ([alg.sorting]).
Effects: Initializes c with first as the first argument and last as the second argument, and initializes comp with x; then calls make_­heap(c.begin(), c.end(), comp).
template<class InputIterator> priority_queue(InputIterator first, InputIterator last, const Compare& x, const Container& y); template<class InputIterator> priority_queue(InputIterator first, InputIterator last, const Compare& x, Container&& y);
Preconditions: x defines a strict weak ordering ([alg.sorting]).
Effects: Initializes comp with x and c with y (copy constructing or move constructing as appropriate); calls c.insert(c.end(), first, last); and finally calls make_­heap(c.begin(), c.end(), comp).
template<container-compatible-range<T> R> priority_queue(from_range_t, R&& rg, const Compare& x = Compare());
Preconditions: x defines a strict weak ordering ([alg.sorting]).
Effects: Initializes comp with x and c with ranges​::​to<Container>(std​::​forward<R>(rg)) and finally calls make_­heap(c.begin(), c.end(), comp).
