Rectangle

To construct a rectangle with sides parallel to the coordinate axes, you need the coordinates of two opposite vertices. Your task is to write a program that calculates the coordinates of the other two vertices of the rectangle.

Input

The input consists of a single line containing four integers $x_1$, $y_1$, $x_2$, $y_2$ (-$1000\le x_1,y_1,x_2,y_2\le 1000$, $x_1\ne x_2$, $y_1\ne y_2$), which represent the coordinates of the given opposite vertices.

Output

Output four integers $x_3$, $y_3$, $x_4$, $y_4$, which are the coordinates of the other two opposite vertices. The coordinates should be printed in the order of the left vertex first, followed by the right vertex.
