``
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`.
