To extract the valid email addresses from the given text, we can use a regular expression that matches the standard email format. The valid emails are those that follow the pattern: a sequence of allowed characters (letters, digits, dots, underscores, percent signs, plus signs, or hyphens) followed by the "@" symbol, then a domain name (which can include letters, digits, dots, or hyphens), and ending with a top-level domain (TLD) of at least two letters. ### Step-by-Step Solution: 1. **Pattern Definition**: The regex pattern `[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}` is used to identify valid email addresses. - `[a-zA-Z0-9._%+-]+`: Matches the username part (one or more allowed characters). - `@`: Matches the "@" symbol. - `[a-zA-Z0-9.-]+`: Matches the domain part (letters, digits, dots, or hyphens). - `\.[a-zA-Z]{2,}`: Matches the TLD (a dot followed by at least two letters). 2. **Extraction**: The regex searches the entire text and finds all matches. The invalid entries do not match this pattern: - `not.an.email.com` lacks an "@" symbol. - `@missing-username.com` has no characters before "@". 3. **Output**: The extracted emails are joined into a comma-separated string without spaces. ### Valid Emails Extracted: - `john.doe@example.com` - `jane@smith-family.net` - `support@company.co.uk` - `info@subdomain.example.org` ### Final Output: ``` john.doe@example.com,jane@smith-family.net,support@company.co.uk,info@subdomain.example.org ```
