There is a rectangle in the xy-plane. Each edge of this rectangle is parallel to the 2or y-axis, and its area is not zero.

Given the coordinates of three of the four vertices of this rectangle, (P,Q), (A,B), and (X,Y), find the coordinates of the other vertex.

### Constraints

All numbers are between -100 and +100.

There uniquely exists a rectangle with all of (P,Q), (A,B), and (X,Y) as vertices, edges parallel to the xor y-axis, and a non-zero area.

All values in input are integers.

### Output

Print the sought coordinates (x,y) separated by a space in the following format:

`R S`

### Sample I/O

`Sample Input 1`

`Sample Output 1`

The other vertex of the rectangle with vertices (−1,−1),(−1,2),(3,2) is (3,−1).
