[heading Description]
|
|
|
|
`next_permutation` transforms the range of elements `rng` into the lexicographically next greater permutation of the elements if such a permutation exists. If one does not exist then the range is transformed into the lexicographically smallest permutation and `false` is returned. `true` is returned when the next greater permutation is successfully generated.
|
|
|
|
The ordering relationship is determined by using `operator<` in the non-predicate versions, and by evaluating `pred` in the predicate versions.
|
|
|
|
[heading Definition]
|
|
|
|
Defined in the header file `boost/range/algorithm/permutation.hpp`
|
|
|
|
[heading Requirements]
|
|
|
|
[*For the non-predicate versions:]
|
|
|
|
* `BidirectionalRange` is a model of the __bidirectional_range__ Concept.
|
|
* `BidirectionalRange` is mutable.
|
|
* `BidirectionalRange`'s value type is a model of the `LessThanComparableConcept`.
|
|
* The ordering of objects of type `BidirectionalRange`'s value type is a [*/strict weak ordering/], as defined in the `LessThanComparableConcept` requirements.
|
|
|
|
[*For the predicate versions:]
|
|
|
|
* `BidirectionalRange` is a model of the __bidirectional_range__ Concept.
|
|
* `BidirectionalRange` is mutable.
|
|
* `Compare` is a model of the `StrictWeakOrderingConcept`.
|
|
* `BidirectionalRange`'s value type is convertible to both of `Compare`'s argument types.
|
|
|
|
[heading Complexity]
|
|
|
|
Linear. At most `distance(rng) / 2` swaps.
