### Rescue The Princess

#### Problem Description

Several days ago, a beast caught a beautiful princess and the princess was put in prison. To rescue the princess, a prince who wanted to marry the princess set out immediately. Yet, the beast set a maze. Only if the prince find out the maze’s exit can he save the princess.

Now, here comes the problem. The maze is a dimensional plane. The beast is smart, and he hidden the princess snugly. He marked two coordinates of an equilateral triangle in the maze. The two marked coordinates are A(x_{1},y_{1}) and B(x_{2},y_{2}). The third coordinate C(x_{3},y_{3}) is the maze’s exit. If the prince can find out the exit, he can save the princess. After the prince comes into the maze, he finds out the A(x_{1},y_{1}) and B(x_{2},y_{2}), but he doesn’t know where the C(x_{3},y_{3}) is. The prince need your help. Can you calculate the C(x_{3},y_{3}) and tell him?

#### Input

The first line is an integer T(1 <= T <= 100) which is the number of test cases. T test cases follow. Each test case contains two coordinates A(x_{1},y_{1}) and B(x_{2},y_{2}), described by four floating-point numbers x_{1}, y_{1}, x_{2}, y_{2} ( |x_{1}|, |y_{1}|, |x_{2}|, |y_{2}|_{ }<= 1000.0).

Please notice that A(x_{1},y_{1}) and B(x_{2},y_{2}) and C(x_{3},y_{3}) are in an anticlockwise direction from the equilateral triangle. And coordinates A(x_{1},y_{1}) and B(x_{2},y_{2}) are given by anticlockwise.

#### Output

_{3},y

_{3}), the result should be rounded to 2 decimal places in a line.
