Rectangle

To construct a rectangle, you need the coordinates of two opposite vertices. The sides of the rectangle are aligned with the coordinate axes. Write a program to determine the coordinates of the other two vertices of the rectangle.

Input

The first line contains four integers $x_1$, $y_1$, $x_2$, $y_2$ (-$1000\le x_1,y_1,x_2,y_2\le 1000$, $x_1\ne x_2$, $y_1\ne y_2$) — these are the coordinates of the given opposite vertices.

Output

Output four integers $x_3$, $y_3$, $x_4$, $y_4$ — the coordinates of the other two vertices, listing the left vertex first, followed by the right vertex.
