Problem 60216. Perfect shuffle
We call "perfect shuffle" the process of cutting a deck of cards into two equal halves, and then perfectly interleaving them: one card from the left stack, one card from the right stack, one card from the left stack, and so on.
Let "deck" be an array with an even number of elements. Write a function "perfect_shuffle(deck)" that returns a new array constructed according to this shuffle.
For example, perfect_shuffle([1, 2, 3, 4, 5, 6]) should return [1, 4, 2, 5, 3, 6].
Remark: For an array of 1024 elements, after 10 shuffles, we get back to the initial arrangement.
