A regular pentagon $P$ is shown in the figure below. ![image](https://img.atcoder.jp/abc333/2d0c9295b03ff6d808c1ee9125045fc8.png) 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: $S_1S_2$ $T_1T_2$ [samples]

Samples

Input #1
