We have the following $3 \times 3$ board with integers from $1$ through $9$ written on it. ![image](https://img.atcoder.jp/abc309/86862b285a60054303435965fe642c67.jpg) You are given two integers $A$ and $B$ between $1$ and $9$, where $A < B$. Determine if the two squares with $A$ and $B$ written on them are adjacent horizontally. ## Constraints * $1 \le A < B \le 9$ * $A$ and $B$ are integers. ## Input The input is given from Standard Input in the following format: $A$ $B$ [samples]
