If a computer has access to purely random numbers, it is capable of generating a "perfect shuffle", a random permutation of the cards; beware that this terminology (an algorithm that perfectly randomizes the deck) differs from "a perfectly executed single shuffle", notably a perfectly interleaving faro shuffle.

When you unshuffle, you must revert the steps: Start lo and hi at the last element for even-sized and one element beyond the array for odd-sized array. Then do all steps in reverse order: decrease lo and hi first, then shift ...
