template<typename_Iterator>constexprstd::reverse_iterator<_Iterator>::reverse_iterator()[inline],[constexpr],[noexcept]
       The default constructor value-initializes member current. If it is a pointer, that means it is zero-
       initialized.

   template<typename_Iterator>constexprstd::reverse_iterator<_Iterator>::reverse_iterator(iterator_type__x)[inline],[explicit],[constexpr],[noexcept]
       This iterator will move in the opposite direction that x does.

   template<typename_Iterator>constexprstd::reverse_iterator<_Iterator>::reverse_iterator(constreverse_iterator<_Iterator>&__x)[inline],[constexpr],[noexcept]
       The copy constructor is normal.

       requires __convertible<_Iter>constexpr std::reverse_iterator< _Iterator >::reverse_iterator (const
       reverse_iterator< _Iter > & __x) [inline],  [constexpr],  [noexcept]" A reverse_iterator across other
       types can be copied if the underlying iterator can be converted to the type of current.

template<typename_Iterator>
       class std::reverse_iterator< _Iterator >"Bidirectional and random access iterators have corresponding
       reverse iterator adaptors that iterate through the data structure in the opposite direction. They have
       the same signatures as the corresponding iterators. The fundamental relation between a reverse iterator
       and its corresponding iterator i is established by the identity:

       &*(reverse_iterator(i)) == &*(i - 1)

       Reverse iterators can be tricky and surprising at first. Their semantics make sense, however, and the
       trickiness is a side effect of the requirement that the iterators must be safe.

template<typename_Iterator>constexpriterator_typestd::reverse_iterator<_Iterator>::base()const[inline],[constexpr],[noexcept]Returns
           current, the iterator used for underlying work.

   template<typename_Iterator>constexprreferencestd::reverse_iterator<_Iterator>::operator*()const[inline],[constexpr]Returns
           A reference to the value at --current

       This requires that --current is dereferenceable.

       Warning
           This implementation requires that for an iterator of the underlying iterator type, x, a reference
           obtained by *x remains valid after x has been modified or destroyed. This is a bug:
           http://gcc.gnu.org/PR51823template<typename_Iterator>constexprreverse_iteratorstd::reverse_iterator<_Iterator>::operator+(difference_type__n)const[inline],[constexpr]Returns
           A reverse_iterator that refers to current - __n

       The underlying iterator must be a Random Access Iterator.

   template<typename_Iterator>constexprreverse_iterator&std::reverse_iterator<_Iterator>::operator++()[inline],[constexpr]Returns
           *this

       Decrements the underlying iterator.

   template<typename_Iterator>constexprreverse_iteratorstd::reverse_iterator<_Iterator>::operator++(int)[inline],[constexpr]Returns
           The original value of *this

       Decrements the underlying iterator.

   template<typename_Iterator>constexprreverse_iterator&std::reverse_iterator<_Iterator>::operator+=(difference_type__n)[inline],[constexpr]Returns
           *this

       Moves the underlying iterator backwards __n steps. The underlying iterator must be a Random Access
       Iterator.

   template<typename_Iterator>constexprreverse_iteratorstd::reverse_iterator<_Iterator>::operator-(difference_type__n)const[inline],[constexpr]Returns
           A reverse_iterator that refers to current - __n

       The underlying iterator must be a Random Access Iterator.

   template<typename_Iterator>constexprreverse_iterator&std::reverse_iterator<_Iterator>::operator--()[inline],[constexpr]Returns
           *this

       Increments the underlying iterator.

   template<typename_Iterator>constexprreverse_iteratorstd::reverse_iterator<_Iterator>::operator--(int)[inline],[constexpr]Returns
           A reverse_iterator with the previous value of *this

       Increments the underlying iterator.

   template<typename_Iterator>constexprreverse_iterator&std::reverse_iterator<_Iterator>::operator-=(difference_type__n)[inline],[constexpr]Returns
           *this

       Moves the underlying iterator forwards __n steps. The underlying iterator must be a Random Access
       Iterator.

   template<typename_Iterator>constexprpointerstd::reverse_iterator<_Iterator>::operator->()const[inline],[constexpr]Returns
           A pointer to the value at --current

       This requires that --current is dereferenceable.

   template<typename_Iterator>constexprreferencestd::reverse_iterator<_Iterator>::operator[](difference_type__n)const[inline],[constexpr]Returns
           The value at current - __n - 1

       The underlying iterator must be a Random Access Iterator.
