[section:swap_ranges swap_ranges]
[heading Prototype]
``
template<class SinglePassRange1, class SinglePassRange2>
SinglePassRange2& swap_ranges(SinglePassRange1& rng1, SinglePassRange& rng2);
``
[heading Description]
`swap_ranges` swaps each element `x` in `rng1` with the corresponding element `y` in `rng2`.
Returns a reference to `rng2`.
[heading Definition]
Defined in the header file `boost/range/algorithm/swap_ranges.hpp`
[heading Requirements]
* `SinglePassRange1` is a model of the __single_pass_range__ Concept.
* `SinglePassRange1` is mutable.
* `SinglePassRange2` is a model of the __single_pass_range__ Concept.
* `SinglePassRange2` is mutable.
[heading Complexity]
Linear. Exactly `distance(rng1)` elements are swapped.
