Problem A
Elliptic Curve Addition

Let $p$ be a prime and $a,b\in {\mathbb{F}}_p$ such that $4a^3+27b^2\not\equiv 0(\mathrm{mod}p)$. Let $P=(x_1,y_1)$ and $Q=(x_2,y_2)$ be two points on the elliptic curve $E:y^2=x^3+ax+b$. Calcuate $P\oplus Q$ given $p,a,b,x_1,y_1,x_2$ and $y_2$.

Input

First line consists of three integers, $0<p<2^{31}-1$, $0\le a<p$ and $0\le b<p$, where $p$ is a prime. Second line consist of two integers $-1\le x_1,y_1<2^{31}-1$ where $(x_1,y_1)=(-1,-1)$ is the point at infinity. Third line consists of two integers $-1\le x_2,y_2<2^{31}-1$ where $(x_2,y_2)=(-1,-1)$ is the point at infinity.

Output

Output one line with the coordinates of $P\oplus Q$ seperated by space. Both coordinates should be $-1$ if the result is the point at infinity.
