103090: [Atcoder]ABC309 A - Nine

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

问题描述

我们有一个包含1到9的$3 \times 3$的棋盘。

给你两个介于1和9之间的整数$A$和$B$，其中$A < B$。

判断写有$A$和$B$的两个方格是否相邻水平。

约束条件

• $1 \le A < B \le 9$
• $A$和$B$是整数。

输入

输入从标准输入按以下格式给出：

$A$ $B$

输出

如果写有$A$和$B$的两个方格相邻水平，则输出Yes，否则输出No。

样例输入1

7 8

样例输出1

Yes

写有$7$和$8$的两个方格相邻水平，所以输出Yes。

样例输入2

1 9

样例输出2

No

样例输入3

3 4

样例输出3

No
