[section:rotate rotate]
[heading Prototype]
``
template<class ForwardRange>
ForwardRange& rotate(ForwardRange& rng,
typename range_iterator<ForwardRange>::type middle);
template<class ForwardRange>
const ForwardRange& rotate(const ForwardRange& rng,
typename range_iterator<const ForwardRange>::type middle);
``
[heading Description]
`rotate` rotates the elements in a range. It exchanges the two ranges `[begin(rng), middle)` and `[middle, end(rng))`. Returns a reference to `rng`.
[heading Definition]
Defined in the header file `boost/range/algorithm/rotate.hpp`
[heading Requirements]
* `ForwardRange` is a model of the __forward_range__ Concept.
* `ForwardRange` is mutable.
[heading Precondition:]
* `[begin(rng), middle)` is a valid range.
* `[middle, end(rng))` is a valid range.
[heading Complexity]
Linear. At most `distance(rng)` swaps are performed.
