public member function
<string>
const_reverse_iterator crbegin() const noexcept;
Return const_reverse_iterator to reverse beginning
Returns a const_reverse_iterator pointing to the last character of the string (i.e., its reverse beginning).
Return Value
A const_reverse_iterator to the reverse beginning of the string.
Member type const_reverse_iterator is a reverse random access iterator type that points to a const character.

Output:
Complexity
Unspecified, but generally constant.
Iterator validity
No changes.
Data races
The object is accessed.
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.
