给定一个字符串和一个数组作为输入，您的任务是输出在典型的移动键盘上键入时输入字符串将打印的文本。在移动键盘中，通过按n次按钮来键入字母，其中n是字母在按钮标签上的位置。因此，22应输出b。

规则

• 辅助数组将包含字符映射表（[" ",".,!","abc","def","ghi","jkl","mno","pqrs","tuv","wxyz"]）。这将为您节省一些字节。

• 该#符号将切换大小写。初始大小写会更低。所以2#3应该输出aD。

• 该0会添加一个空格。因此，202应输出a a。

• 输入的字符串中将有一个空格（），以在同一数字按钮上开始一个新字母。例如，键入时aa，输入String为2 2。

• 保证输入的String始终是有效的键盘代码。

输入值

您可以使用您的语言支持的任何方式进行输入。

输出量

您可以按任何方式输出结果。功能return也是允许的。
