of any size that are part of the original sequence.
Namespace: MoreLinq

SyntaxParameters
- sequence
- Type: System.Collections.GenericIEnumerableT
Sequence for which to produce subsets
Type Parameters
- T

Return Value
Type: IEnumerableIListTA sequence of lists that represent the all subsets of the original sequence
Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type IEnumerableT. When you use instance method syntax to call this method, omit the first parameter.

Remarks
This operator produces all of the subsets of a given sequence. Subsets are returned
in increasing cardinality, starting with the empty set and terminating with the
entire original sequence.
Subsets are produced in a deferred, streaming manner; however, each subset is returned as a materialized list.
There are 2^N subsets of a given sequence, where N => sequence.Count().
