A shuffle of 2n cards puts the first n cards in the odd positions and the last n cards in the even positions.[For example shuffle (1,2,3,4,5,6) and you get (1,4,2,5,3,6).] Heather has 10 cards, 1-10, Briana has 12 cards, 1-12. Each shuffles her deck 2000 times. "Hey, my deck is back to its original state!"

Who said that, and which card does the other deck have in position #5?
