There are $7$ points $A$, $B$, $C$, $D$, $E$, $F$, and $G$ on a straight line, in this order. (See also the figure below.) The distances between adjacent points are as follows. * Between $A$ and $B$: $3$ * Between $B$ and $C$: $1$ * Between $C$ and $D$: $4$ * Between $D$ and $E$: $1$ * Between $E$ and $F$: $5$ * Between $F$ and $G$: $9$ ![image](https://img.atcoder.jp/ghi/abc305b_33d2c7bcdf92725cf9145e524f6907c76fd1f50fe06fd37b511b8bd3c27e3638.jpg) You are given two uppercase English letters $p$ and $q$. Each of $p$ and $q$ is `A`, `B`, `C`, `D`, `E`, `F`, or `G`, and it holds that $p \neq q$. Find the distance between the points $p$ and $q$. ## Constraints * Each of $p$ and $q$ is `A`,`B`,`C`,`D`,`E`,`F`, or `G`. * $p \neq q$ ## Input The input is given from Standard Input in the following format: $p$ $q$ [samples]
