```python
def string_mapping(s): mapping = {'a': '1', 'b': '2', 'c': '3', 'd': '4', 'e': '5', 'f': '6', 'g': '7', 'h': '8', 'i': '9', 'j '10*', 'k': '11* result = "" for char in s: if char in mapping: result = mapping[char] return result
input_string = input("请输入一段字符串: ") output_string = string_mapping(input_string) print("映射后的字符串为:", output_string)
```
运行以上代码，用户可以输入一段字符串，程序将对字符串进行规则映射并输出。
