Reverse
=======

Include :file:`<mln/core/ranges/view/reverse.hpp>`

.. cpp:namespace:: mln::ranges

.. cpp:function:: auto view::reverse(ReversibleRange r)

   :param r: Input range

   If the expression :cpp:expr:`r.reversed()` is valid, then it is
   returned. Otherwise, `r` must model the concept :cpp:concept:`BidirectionalRange <std::BidirectionalRange>`
   and the function returns ``::ranges::view::reverse(rng)``. This view preserves the following properties:

   **Examples**
   
   * Browse a box2d's indexes reversly:

      .. code-block:: cpp

         mln::box2d box = {{0,0}, {2,3}};
         mln_foreach(auto p, ranges::view::reverse(box))
           std::cout << p << ",";


      Outputs:

         .. code-block:: text

            (1,2),(1,1),(1,0),(0,2),(0,1),(0,0),
