void push( const T& value );
void push( T&& 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);

Parameters

value

-

the value of the element to push

Return value

(none)

Complexity

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