## Problem: Find Point

*Difficulty: Baby step

Problem:

Given two points P and Q, output the symmetric point of point P about Q.

**Input Format**

The first line contains an integer representing the number of testcases

Each test case is a line containing four space separated integers Px Py Qx Qy representing the (x,y) coordinates of P and Q.

**Constraints**

```
1 <= T <= 15
-100 <= x,y <= 100
```

**Output Format**

For each test case output x and y coordinates of the symmetric point (each point in a new line).

**Sample Input**

```
2
0 0 1 1
1 1 2 2
```

**Sample Output**

```
2 2
3 3
```

How to solve:

Suppose we got two point A(x,y) and B(x,y) the formula to calculate the coordinates of the middle point is:

midx = (xA + xB )/ 2

midy = (yA + yB)/ 2

We already have the middle point and A, we just need to find xB

xB = 2*midX – xA

yB = 2*midY – yA

Supper easy
