Problem:
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

Solution in Rust (1.15.1) (judge verdict: Accepted)

use std::io;
use std::io::BufRead;
use std::io::BufReader;

fn main() {
    let reader = io::stdin();
    let mut reader = BufReader::new(reader.lock());

    let mut s = String::new();

    let _ = reader.read_line(&mut s);

    let xs: Vec<i32> = s.split_whitespace().map(|x| x.parse().unwrap()).collect();

    let x1 = xs[0];
    let y1 = xs[1];
    let x2 = xs[2];
    let y2 = xs[3];

    let dis_x = x2 - x1;
    let dis_y = y2 - y1;

    println!("{} {} {} {}", x2 - dis_y, y2 + dis_x, x1 - dis_y, y1 + dis_x);
}
