Actually, it's not correct. The wording of the puzzle indicates that at least two operations have already been performed: > You cut a slice, > turn the slice over and put it back, then cut another slice adjacent to > the first one and turn that over and put it back, and so forth, always > moving clockwise. The puzzle then asks if it's ever possible to return from such a state to the original state. 0 operations would leave the cake still partially flipped. -root
