Let us define a sequence as below

$$\left\{\begin{eqnarray*}
F_1 &=& A \\
F_2 &=& B \\
F_n &=& C\cdot{}F_{n-2}+D\cdot{}F_{n-1}+\left\lfloor\frac{P}{n}\right\rfloor
\end{eqnarray*}\right.$$

  Your job is simple, for each task, you should output $F_n$ module $10^9+7$.

The first line has only one integer $T$, indicates the number of tasks.

Then, for the next $T$ lines, each line consists of $6$ integers, $A$ , $B$, $C$, $D$, $P$, $n$.

$1 \leq T \leq 20 \\
0 \leq A, B, C, D \leq 10^9 \\
1 \leq P, n \leq 10^9$
