template<class RandomAccessIterator> constexpr void pop_heap(RandomAccessIterator first, RandomAccessIterator last); template<class RandomAccessIterator, class Compare> constexpr 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 Cpp17ValueSwappable requirements ([swappable.requirements]).
The type of *first shall satisfy the Cpp17MoveConstructible (Table 25) and Cpp17MoveAssignable (Table 27) requirements.
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 comparisons.
