 Sort through all of the parts you've been given; **what do you get if you add together all of the rating numbers for

+# Part Two
+Even with your help, the sorting process **still** isn't fast enough.
+
+One of the Elves comes up with a new plan: rather than sort parts individually through all of these workflows, maybe 
+you can figure out in advance which combinations of ratings will be accepted or rejected.
+
+Each of the four ratings (`x`, `m`, `a`, `s`) can have an integer value ranging from a minimum of `1` to a maximum of 
+`4000`. Of **all possible distinct combinations** of ratings, your job is to figure out which ones will be **accepted**.
+
+In the above example, there are **`167409079868000`** distinct combinations of ratings that will be accepted.
+
+Consider only your list of workflows; the list of part ratings that the Elves wanted you to sort is no longer relevant. 
+**How many distinct combinations of ratings will be accepted by the Elves' workflows**?
