To use the calculator, you would input the list of strings and the regular expression pattern. The calculator would then split the strings based on the pattern and display each group along with its group key. Each string is tested for a match, if match is found, it becomes the group key, and string is assigned to this group. Thus you are splitting the list to groups.
For example, if you have a list of email addresses from three different domains (example.com, example.org, and example.net), you could use a regular expression to match each domain. The regular expression might look something like this: @example.(com|org|net).
When you run the calculator, it would split the email addresses into three groups based on the domain name, and display each group along with its domain name. This would allow you to quickly and easily analyze the email addresses by domain.
The regular expression splitter can be useful in many different situations where you need to split a list of strings based on a specific pattern. It can help you to quickly group data and analyze it in a more meaningful way.
