  Difficulty: Easy   Marks: 2

Given three coordinate points A, B and C, find the missing point D such that ABCD can be a parallelogram. There can be multiple such points, so print the lexicographically least coordinate.

Input:
The first line of input contains an integer T denoting the number of test cases. Each test case contains three lines for each of the point A, B and C with each line containing space separated integers Xi and Yi as coordinates for each of them.

Output:
Print two space separated coordinates of the required point with a precision of 6 decimal places.

Constraints:
1<=T<=100
1<=x,y<=1000 where x and y denote coordinates of points.

Example:
Input:

2
1 1
1 0
0 1
3 2
3 4
2 2

Output:
0.000000 0.000000
2.000000 0.000000
