102460: [AtCoder]ABC246 A - Four Points

Problem Statement

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

Given the coordinates of three of the four vertices of this rectangle, $(x_1, y_1)$, $(x_2, y_2)$, and $(x_3, y_3)$, find the coordinates of the other vertex.

Constraints

• $-100 \leq x_i, y_i \leq 100$
• There uniquely exists a rectangle with all of $(x_1, y_1)$, $(x_2, y_2)$, $(x_3, y_3)$ as vertices, edges parallel to the $x$- or $y$-axis, and a non-zero area.
• All values in input are integers.

Input

Input is given from Standard Input in the following format:

$x_1$ $y_1$
$x_2$ $y_2$
$x_3$ $y_3$

Output

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

$x$ $y$

Sample Input 1

-1 -1
-1 2
3 2

Sample Output 1

3 -1

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

Sample Input 2

-60 -40
-60 -80
-20 -80

Sample Output 2

-20 -40

问题描述

在$xy$平面上有一个矩形。这个矩形的每条边都与$x$轴或$y$轴平行，且面积不为零。

给定这个矩形四个顶点中的三个顶点的坐标$(x_1, y_1)$、$(x_2, y_2)$和$(x_3, y_3)$，找出第四个顶点的坐标。

限制条件

• $-100 \leq x_i, y_i \leq 100$
• 存在一个矩形，其所有顶点为$(x_1, y_1)$、$(x_2, y_2)$、$(x_3, y_3)$，边与$x$轴或$y$轴平行，面积非零，并且是唯一的。
• 输入中的所有值都是整数。

输入

从标准输入按以下格式获取输入：

$x_1$ $y_1$
$x_2$ $y_2$
$x_3$ $y_3$

输出

按以下格式打印目标坐标$(x, y)$，用空格分隔：

$x$ $y$
