$\hspace{15pt}$ 规定这样一种密码的变换方法：
$\hspace{23pt}\bullet\,$ 对于密码中的小写字母，参考九键手机键盘，将它们映射为对应的数字，具体地， $\mathtt{abc}$ 对应数字 $2$ 、 $\mathtt{def}$ 对应数字 $3$ 、 $\mathtt{ghi}$ 对应数字 $4$ 、 $\mathtt{jkl}$ 对应数字 $5$ 、 $\mathtt{mno}$ 对应数字 $6$ 、 $\mathtt{pqrs}$ 对应数字 $7$ 、 $\mathtt{tuv}$ 对应数字 $8$ 、 $\mathtt{wxyz}$ 对应数字 $9$ ；
$\hspace{23pt}\bullet\,$ 对于密码中的大写字母，先将其转换为小写，然后向后移动一位，即 $\mathtt{Z}$ 转换为 $\mathtt{a}$ ， $\mathtt{A}$ 转换为 $\mathtt{b}$ ， $\mathtt{B}$ 转换为 $\mathtt{c}$ ， $\cdots$ ， $\mathtt{Y}$ 转换为 $\mathtt{z}$ ， $\mathtt{Z}$ 转换为 $\mathtt{a}$ 。
$\hspace{23pt}\bullet\,$ 对于密码中的数字，保持不变。

$\hspace{15pt}$ 现在，请你将给定的密码按照上述规则进行变换。

输入描述:

在一行上输入一个长度为  的字符串  ，代表给定的密码。

输出描述:

在一行上输出一个字符串，代表变换后的密码。
