We take 14 cards from a pack: ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, jack, queen, king and another ace, and arrange them in a 3 by 5 rectangle with one empty space, as shown in the diagram.
The aim is to rearrange the cards so that, reading from left to right, the top row contains A, 2, 3, 4, 5; the middle row 6, 7, 8, 9, 10; and the bottom row J, Q, K, A followed by a space.
To do this, you are allowed to slide any card horizontally or vertically into the empty spot (thus creating a new empty spot).
For example, you could move the king to the right, then the black ace to the right, then the 8 downwards, and so on. If this is your answer, just send us a list of the cards you move: K, BA, 8. And so on…
