ThisIn the second test, this counts [1,2,3] as four ways to get 6, since [in 2nd test] there are two 1s and two 3s... ("order unimportant")

=== very silly way ===
ThisIn the second test, this counts [1,2,3] as 24 ways to get 6, from 2 1s, 2 3s [in 2nd test], and 6 ways to order them ("order important")
