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