I have an ArrayList 'System.Collections.ArrayList' in Powershell which contains a number of numeric items e.g. 5, 10. I am looking for a way I can find all subsets of this array so for the example here it would be...
The order of the sets is not important so set (5, 10) is the same as (10, 5) and am empty set should not count... In reality the array list I have is much larger - any ideas?
