28.7.7.2 pop_­heap [pop.heap]

template<class RandomAccessIterator> void pop_heap(RandomAccessIterator first, RandomAccessIterator last); template<class RandomAccessIterator, class Compare> void pop_heap(RandomAccessIterator first, RandomAccessIterator last, Compare comp);
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.
Effects: Swaps the value in the location first with the value in the location last - 1 and makes [first, last - 1) into a heap.
Complexity: At most comparisons.
