std::priority_queue::push

void push( const value_type& value );
void push( value_type&& value );		(since C++11)

Pushes the given element value to the priority queue.

1) Effectively calls c.push_back(value); std::push_heap(c.begin(), c.end(), comp);

2) Effectively calls c.push_back(std::move(value)); std::push_heap(c.begin(), c.end(), comp);

value

the value of the element to push

(none).

Logarithmic number of comparisons plus the complexity of Container::push_back.

emplace (C++11)	constructs element in-place and sorts the underlying container (public member function)
pop	removes the top element (public member function)
