Q is the number of iteration.

let me explain you the sample test case with q=3
.5 3
3 4 7 6 5
after 1st iteration (1st prime no is 2)
A1->5,7,3
B1->6,4
now 2 nd iteration (2 nd prime no is 3)
A2->7,5
B2->3
now 3 rd iteration ( 3 rd prime no is 5)
A3->7
B3->5
Output numbers on these cards from top to bottom of each piles in order of B1, B2, B3,A3.
