Perl algorithm to iterate through subsets of a list.
|
|
|
|
"Subsets" in this context refers to lists with elements taken
|
|
from the original list, and in the same order as the elements in the
|
|
original list. After creating the object, subsequent calls to next()
|
|
will return the next such list in lexicographic order (where the alphabet
|
|
is the original list).
