You are given two arrays $a_0, a_1, \ldots, a_{n - 1}$ and $b_0, b_1, \ldots, b_{m-1}$, and an integer $c$.

Compute the following sum:

$$\sum_{i=0}^{n-1} \sum_{j=0}^{m-1} a_i b_j c^{i^2\,j^3}$$

Since it's value can be really large, print it modulo $490019$.

Input

First line contains three integers $n$, $m$ and $c$ ($1 \le n, m \le 100\,000$, $1 \le c \lt 490019$).

Next line contains exactly $n$ integers $a_i$ and defines the array $a$ ($0 \le a_i \le 1000$).

Last line contains exactly $m$ integers $b_i$ and defines the array $b$ ($0 \le b_i \le 1000$).

Output

Print one integer — value of the sum modulo $490019$.

Note

In the first example, the only non-zero summand corresponds to $i = 1$, $j = 1$ and is equal to $1 \cdot 1 \cdot 3^1 = 3$.

In the second example, all summands are equal to $1$.
