AT_abc474_a.Not X

You are given an integer $X$ between $1$ and $3$, inclusive.

Output an integer between $1$ and $3$, inclusive, that is different from $X$.

给你一个在 $1$ 到 $3$（含）之间的整数 $X$。

输出一个在 $1$ 到 $3$（含）之间的整数，且该整数不等于 $X$。

The input is given from Standard Input in the following format:

$X$

输入从标准输入中按以下格式给出：

$X$

Output an integer between $1$ and $3$, inclusive, that is different from $X$.

If there are multiple integers satisfying the condition, any of them will be accepted.

输出一个在 $1$ 到 $3$（含）之间的整数，且该整数不等于 $X$。

如果存在多个满足条件的整数，则其中任意一个均可接受。

Sample 1 Explanation:
The integers between $1$ and $3$, inclusive, that are different from $X(=1)$ are $2$ and $3$.

Thus, outputing either $2$ or $3$ will be accepted.

Constraints

• $X$ is an integer between $1$ and $3$, inclusive.

样例 1 解释：
在 $1$ 到 $3$（含端点）之间的整数中，与 $X(=1)$ 不同的数是 $2$ 和 $3$。

因此，输出 $2$ 或 $3$ 中的任意一个均可接受。

限制条件

• $X$ 是一个介于 $1$ 和 $3$（含端点）之间的整数。
