| 30 | [heading Description] |
| 31 | |
| 32 | `search_n` searches `rng` for a sequence of length `n` equal to `value` where |
| 33 | equality is determined by operator== in the non-predicate case, and by a |
| 34 | predicate when one is supplied. |
| 35 | |
| 36 | [heading Definition] |
| 37 | |
| 38 | Defined in the header file `boost/range/algorithm/search_n.hpp` |
| 39 | |
| 40 | [heading Requirements] |
| 41 | |
| 42 | [*For the non-predicate versions:] |
| 43 | |
| 44 | * `ForwardRange` is a model of the __forward_range__ Concept. |
| 45 | * `ForwardRange`'s value type is a model of the `EqualityComparableConcept`. |
| 46 | * `ForwardRange`s value type can be compared for equality with `Value`. |
| 47 | * `Integer` is a model of the `IntegerConcept`. |
| 48 | |
| 49 | [*For the predicate versions:] |
| 50 | |
| 51 | * `ForwardRange` is a model of the __forward_range__ Concept. |
| 52 | * `BinaryPredicate` is a model of the `BinaryPredicateConcept`. |
| 53 | * `ForwardRange`'s value type is convertible to `BinaryPredicate`'s first argument type. |
| 54 | * `Value` is convertible to `BinaryPredicate`'s second argument type. |
| 55 | * `Integer` is a model of the `IntegerConcept`. |

| 57 | [heading Complexity] |
| 58 | |
| 59 | Average complexity is Linear. Worst-case complexity is quadratic. |
