No. Let the number of stones

in the three piles be \(a, b\) and \(c\),

respectively. Consider (mod \(3\)) of these

numbers. In the beginning, they are \(1, 2, 0\). After one operation, they become \(0, 1, 2\) no matter which two piles have stones

transfer to the third pile. So the

remainders are always \(0, 1, 2\) in some

order. Therefore, all piles having \(12 \) stones are impossible. -
