Write 12 examples of regex strings using proper syntax. Display in table format. In the first column, write the string. In the second column, write what it does. In the third column, write where you would use it, and where it should be included in your file. In the fourth column, break it down and explain each part in detail.

Other than the characters you listed, what can \s match?

Here are some additional details about \s and regular expressions:
- \s matches whitespace characters including space, tab, newline, line feed, and carriage return
- Regex can use a variety of special characters and syntax to create flexible matching patterns
- More complex patterns can be constructed using | for OR expressions, () for grouping, {} for quantifiers, etc.
- Flags and modifiers like i for case-insensitive and g for global matching can control how the regex engine interprets the pattern
- Testing regex patterns with online tools or debuggers is useful to check for accuracy and fix any issues
- There are many resources and tutorials online that provide in-depth explanations and practical examples of how to write and use powerful regular expressions
