There is a rectangle in the $xy$-plane. Each edge of this rectangle is parallel to the $x$- or $y$-axis, and its area is not zero. Given the coordinates of three of the four vertices of this rectangle, $(x_1, y_1)$, $(x_2, y_2)$, and $(x_3, y_3)$, find the coordinates of the other vertex.Problem Statement
Constraints
Input
Input is given from Standard Input in the following format:
$x_1$ $y_1$ $x_2$ $y_2$ $x_3$ $y_3$
Output
Print the sought coordinates $(x, y)$ separated by a space in the following format:
$x$ $y$
Sample Input 1
-1 -1 -1 2 3 2
Sample Output 1
3 -1
The other vertex of the rectangle with vertices $(-1, -1), (-1, 2), (3, 2)$ is $(3, -1)$.
Sample Input 2
-60 -40 -60 -80 -20 -80
Sample Output 2
-20 -40
