[heading Prototype]

``
template<class BidirectionalRange>
BidirectionalRange& reverse(BidirectionalRange& rng);

template<class BidirectionalRange>
const BidirectionalRange& reverse(const BidirectionalRange& rng);
``

[heading Description]

`reverse` reverses a range. Returns a reference to the reversed range.

[heading Definition]

Defined in the header file `boost/range/algorithm/reverse.hpp`

[heading Requirements]

* `BidirectionalRange` is a model of the __bidirectional_range__ Concept.
* `BidirectionalRange` is mutable.

[heading Complexity]

Linear. `reverse` makes `distance(rng)/2` calls to `iter_swap`.
