#
Requires: The range [first, last) shall be a valid heap.
RandomAccessIterator shall satisfy the Cpp17ValueSwappable requirements ([swappable.requirements]).
The type of *first shall satisfy the Cpp17MoveConstructible (Table 25) and Cpp17MoveAssignable (Table 27) requirements.

Effects: Sorts elements in the heap [first, last).
