问题描述

我们有一个如下的 $3 \times 3$ 矩阵，上面写有从 $1$ 到 $9$ 的整数。

已知两个整数 $A$ 和 $B$，它们都在 $1$ 到 $9$ 之间，并且满足 $A < B$。

请确定标有 $A$ 和 $B$ 的两个方格是否在水平方向上相邻。

Problem Statement

We have the following $3 \times 3$ board with integers from $1$ through $9$ written on it.

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:

$A$ $B$

Output

Print Yes if the two squares with $A$ and $B$ written on them are adjacent horizontally, and No otherwise.

Sample Input 1

7 8

Sample Output 1

Yes

The two squares with $7$ and $8$ written on them are adjacent horizontally, so print Yes.

Sample Input 2

1 9

Sample Output 2

No

Sample Input 3

3 4

Sample Output 3

No
