Priority queue is a container that allows for constant time maximum (or minimum, depending on Compare) extraction at the expense of logarithmic insertion. Working with a priority_queue is similar to managing a heap in some random access container, with the benefit of not being able to accidentally invalidate the heap.

Member types

Member type	Definition
container_type	Container
value_type	Container::value_type

operator=	컨테이너 어댑터에 값을 할당한다. (public member function)
Element access
top	access the top element (public member function)
Capacity
empty	현재 컨테이너가 비어있는지 확인한다. (public member function)

swap	원소들을 서로 바꾼다 (public member function)
Member objects
Container c	the underlying container (protected member object)
Compare comp	the comparison function object (protected member object)
