Tanjiro found a sequence written in the wall of the library which will give him the serial number of the book. As tanjiro is super bad at math he wants your help to solve the following sequence.


The input begins with the number of cases T (1 ≤ T ≤ 10,0000). In each of the following T lines you will find four non negative integers: A, n, k, m. Here k is a power of 2(2x=k2^x = k).

1 <= A <= 10^6

1 <= m <= 1000

1 <= k <= 20

1 <= n <= 10^6


For each case, output the value of the sequence S.
