The game of circulate is played with a deck of
cards each with a number in
such that there are
cards with each number. First,
piles numbered
of
cards each are dealt out face down. The player then flips over a card from pile
, places that card face up at the bottom of the pile, then next flips over a card from the pile whose number matches the number on the card just flipped. The player repeats this until he reaches a pile in which every card has already been flipped and wins if at that point every card has been flipped. Hamster has grown tired of losing every time, so he decides to cheat. He looks at the piles beforehand and rearranges the
cards in each pile as he pleases. When can Hamster perform this procedure such that he will win the game?
