Returns a reverse iterator past the last element of the reversed*this. It corresponds to the element preceding the first element of the non-reversed*this.
This returned iterator only acts as a sentinel. It is not guaranteed to bedereferenceable.

Reverse iterator to the element following the last element.
Constant.
Because bothiterator
andconst_iterator
are constant iterators (and may in fact be the same type), it is not possible to mutate the elements of the container through an iterator returned by any of these member functions.
