template<class RandomAccessIterator> void pop_heap(RandomAccessIterator first, RandomAccessIterator last); template<class RandomAccessIterator, class Compare> void pop_heap(RandomAccessIterator first, RandomAccessIterator last, Compare comp);

1
#

Requires: The range [first, last) shall be a valid non-empty heap. RandomAccessIterator shall satisfy the requirements of ValueSwappable. The type of *first shall satisfy the requirements of MoveConstructible and of MoveAssignable.

2
#

Effects: Swaps the value in the location first with the value in the location last - 1 and makes [first, last - 1) into a heap.

3
#

Complexity: At most 2log(last - first) comparisons.
