103331: [Atcoder]ABC333 B - Pentagon

Problem Statement

A regular pentagon $P$ is shown in the figure below.

Determine whether the length of the line segment connecting points $S_1$ and $S_2$ of $P$ equals the length of the line segment connecting points $T_1$ and $T_2$.

Constraints

• Each of $S_1$, $S_2$, $T_1$, and $T_2$ is one of the characters A, B, C, D, and E.
• $S_1 \neq S_2$
• $T_1 \neq T_2$

Input

The input is given from Standard Input in the following format:

$S_1S_2$
$T_1T_2$

Output

If the length of the line segment connecting points $S_1$ and $S_2$ of $P$ equals the length of the line segment connecting points $T_1$ and $T_2$, print Yes; otherwise, print No.

问题描述

如图所示，正五边形$P$。

判断$P$中连接点$S_1$和$S_2$的线段长度是否等于连接点$T_1$和$T_2$的线段长度。

约束条件

• 每个$S_1$、$S_2$、$T_1$和$T_2$是字符A、B、C、D和E中的一个。
• $S_1 \neq S_2$
• $T_1 \neq T_2$

输入

输入从标准输入按以下格式给出：

$S_1S_2$
$T_1T_2$

输出

如果$P$中连接点$S_1$和$S_2$的线段长度等于连接点$T_1$和$T_2$的线段长度，打印Yes；否则，打印No。
