Problem Statement

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.

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

Constraints

• -$100 \leq x_i, y_i \leq 100$
• There uniquely exists a rectangle with all of (x_1, y_1), (x_2, y_2), (x_3, y_3) as vertices, edges parallel to the x- or y-axis, and a non-zero area.
• All values in input are integers.

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
