public static IEnumerable<int[]> Permutations(
int count,
int length,
bool lexicographic
)Parameters
- count Int32
- The size of the set to draw permutations from.
- length Int32
- The length of each permutation.
- lexicographic Boolean
- Specifies whether the permutations should be returned in lexicographic order.
Return Value
IEnumerable<Int32[]>A sequence of integer arrays that contain the indexes of all permutations from a set of size count. If lexicographic is true, then the permutations are returned in lexicographic order.
Remarks
When lexicographic order is not required, it is faster to set lexicographic to false.
