To extract valid email addresses from the provided text, we use a regular expression that matches standard email patterns. The regex `\b[\w.%+-]+@[\w.-]+\.[a-zA-Z]{2,}\b` ensures: - **Local part**: Alphanumeric characters, dots, underscores, `%`, `+`, and `-`. - **Domain**: Alphanumeric characters, dots, and hyphens. - **TLD**: At least two alphabetic characters (e.g., `.com`, `.co.uk`). This pattern excludes invalid entries (e.g., missing `@`, no local part, or TLD too short). ### Step-by-Step Extraction: 1. **Text Input**: ``` Contact information: 1. John Doe - john.doe@example.com 2. Jane Smith - jane@smith-family.net 3. support@company.co.uk 4. info@subdomain.example.org 5. Invalid email: not.an.email.com 6. Another invalid: @missing-username.com ``` 2. **Apply Regex**: - `john.doe@example.com`: Matches (valid). - `jane@smith-family.net`: Matches (valid). - `support@company.co.uk`: Matches (valid). - `info@subdomain.example.org`: Matches (valid). - `not.an.email.com`: No `@` → **excluded**. - `@missing-username.com`: No local part → **excluded**. 3. **Output**: Comma-separated list of valid emails without spaces: `john.doe@example.com,jane@smith-family.net,support@company.co.uk,info@subdomain.example.org` ### Final Answer: john.doe@example.com,jane@smith-family.net,support@company.co.uk,info@subdomain.example.org
