One simple solution would be to use the Ramp function to create an array of numbers from 0 to 10 and then the Riffle function.
Assuming this actually is a homework problem... that would be a very interesting solution. If someone handed that to me I don't know if I'd be mad because they obviously didn't do the assignment as I intended, or impressed that they came up with the workaround
And I would give it an A+. The problem is essentially "Shuffle the deck" (where here "deck" has only Ace of spades through the 10 of spades). I'm curious how the Riffle function works -- there is a known "most optimum" method of randomly ordering a set of size N (10, in this case). Famous Darren presented a fascinating talk a few years ago where he presented the "Texas Lottery Problem", namely drawing N lottery balls from a set of M (maybe 5 from 52? I don't remember). He presented 3-4 ways to do it, had the audience "vote" on which would be fastest, and almost all of us (including me) were wrong. But I raised my hand and said "But I can do it even faster using the correct Shuffle Algorithm" -- fortunately, I turned out to be right, but not by much ...
