Extracting the first, last, and middle name from an email ID is not straightforward because email IDs typically do not directly provide such information. However, if we make some assumptions based on common patterns in email IDs, we can attempt to extract the first and last names. Middle names are not typically included in email IDs, so we won't attempt to extract them.
Here's how we can approximate the first and last names from the given email IDs:
For riteshsinghsainik@gmail.com, we assume "Ritesh" as the first name and "Singh Sainik" as the last name (assuming "Singh Sainik" is a compound last name).
These assumptions are based on common naming conventions found in email IDs, but they may not always be accurate or applicable universally. Email IDs are generally not designed to provide structured names in a way that software can reliably parse first and last names without additional context or user input.
