﻿ ABC108 B - Ruined Square - Atcoder

# Home

Score : $200$ points

### Problem Statement

There is a square in the $xy$-plane. The coordinates of its four vertices are $(x_1,y_1),(x_2,y_2),(x_3,y_3)$ and $(x_4,y_4)$ in counter-clockwise order. (Assume that the positive $x$-axis points right, and the positive $y$-axis points up.)

Takahashi remembers $(x_1,y_1)$ and $(x_2,y_2)$, but he has forgot $(x_3,y_3)$ and $(x_4,y_4)$.

Given $x_1,x_2,y_1,y_2$, restore $x_3,y_3,x_4,y_4$. It can be shown that $x_3,y_3,x_4$ and $y_4$ uniquely exist and have integer values.

### Constraints

• $|x_1|,|y_1|,|x_2|,|y_2| \leq 100$
• $(x_1,y_1)$ ≠ $(x_2,y_2)$
• All values in input are integers.

### Input

Input is given from Standard Input in the following format:

$x_1$ $y_1$ $x_2$ $y_2$


### Output

Print $x_3,y_3,x_4$ and $y_4$ as integers, in this order.

### Sample Input 1

0 0 0 1


### Sample Output 1

-1 1 -1 0


$(0,0),(0,1),(-1,1),(-1,0)$ is the four vertices of a square in counter-clockwise order. Note that $(x_3,y_3)=(1,1),(x_4,y_4)=(1,0)$ is not accepted, as the vertices are in clockwise order.

### Sample Input 2

2 3 6 6


### Sample Output 2

3 10 -1 7


### Sample Input 3

31 -41 -59 26


### Sample Output 3

-126 -64 -36 -131
