Separate Characters

Given a string s, your task is to separate it into three parts:

• Lowercase letters: All lowercase alphabetic characters in the order they appear.
• Digits: All numeric characters in the order they appear.
• Special characters: All characters that are neither lowercase letters nor digits, in the order they appear.

If a category has no characters, output an empty line for that category.

Note: The program should read the input from standard input (stdin) and write the output to standard output (stdout).

inputFormat

The input consists of a single string s which may contain lowercase letters, digits, and special characters. The string is provided via standard input.

outputFormat

The output should contain three lines:

1. The first line should contain all lowercase letters extracted from the input.
2. The second line should contain all digit characters extracted from the input.
3. The third line should contain all special characters extracted from the input.

If a particular category has no characters, print an empty line for that category.
