Two friends were stuck in a cottage. They had nothing to do and thus they started playing cards. Suddenly the power went off and Friend 1 inverted the position of 15 cards in the normal deck of 52 cards and shuffled it.

On checking, the count of cards facing up is same in both the piles. How could Friend 2 have done it ?
