public member function
<set>
const_reverse_iterator crend() const noexcept;
Return const_reverse_iterator to reverse end
Returns a const_reverse_iterator pointing to the element that would theoretically precede the first element in the container (which is considered its reverse end).
Return Value
A const_reverse_iterator to the reverse end of the sequence.
Member type const_reverse_iterator is a bidirectional iterator type that points to const elements.

std::cout << "mymultiset backwards:";

Output:
mymultiset backwards: 30 20 20 10 10

Iterator validity
No changes.
Data races
The container is accessed.
Concurrently accessing the elements of a multiset is safe.
Exception safety
No-throw guarantee: this member function never throws exceptions.
The copy construction or assignment of the returned iterator is also guaranteed to never throw.
