Subject Re: [Collections] "For each pair" iterator
Date Wed, 02 Apr 2008 16:20:37 GMT
Hi,

What I'd like to do is iterate through each subset of size 2 of a Set.

Example:

My set is: S = {1,2,3,4}
I'd like to iterate throught every one of these subsets:
{1,2}, {1,3}, {1,4}, {2,3}, {2,4} and {3,4}.
