Consider two points, $p=(p_x,p_y)$ and $q=(q_x,q_y)$. We consider the inversion or point reflection, $r=(r_x,r_y)$, of point ${p}$ across point ${q}$ to be a ${180^{\circ}}$ rotation of point ${p}$ around ${q}$.

Given $n$ sets of points ${p}$ and ${q}$, find ${r}$ for each pair of points and print two space-separated integers denoting the respective values of $r_{x}$ and $r_{y}$ on a new line.

Function Description

Complete the findPoint function in the editor below.

findPoint has the following parameters:

int px, py, qx, qy: x and y coordinates for points ${p}$ and $q}$

Returns

int[2]: x and y coordinates of the reflected point ${r}$

Input Format

The first line contains an integer, $n$, denoting the number of sets of points.

Each of the $n$ subsequent lines contains four space-separated integers that describe the respective values of $\boldsymbol{p_{x}}$, $p_y$, $q_{x}$, and $q_y$ defining points $p=(p_x,p_y)$ and $q=(q_x,q_y)$.

Constraints

$1\leq n\leq15$
$-100\leq p_x,p_y,q_x,q_y\leq100$
