I came up with an algorithm to find a Cartesian product of multiple IEnumerable sets. I was able to achieve lazy enumeration via yield return, but I didn't think of a way to do it non-recursively. The result ended up being a recursive lazy enumeration iterator method, the first of it's kind. At l...
Everything works with this program. It takes both Strings and ints, however, I feel like my add method is simply too verbose. Does anyone believe I can implement a shorter version of this, or is it good as is?
Note: Nothing can be changed in any of the method signatures or parameters. The only ...
