This question runs in a pre-configured Salesforce environment - no personal connection required.
Query the Contact object and return a list of full names for all contacts where the Phone field is null. Format each name as "FirstName LastName". If a contact has no FirstName, use only the LastName. Order the results by LastName, then FirstName. Limit to 200 records.
Examples:
Input: (no parameters - queries org data)
Output: ['Alice Lee', 'Bob Johnson', 'Jane Smith']
Explanation: Returns names of all contacts that have no phone number on file, ordered by last name then first name
Input: (no contacts without phone in the org)
Output: []
Explanation: Returns an empty list when all contacts have a phone number
Input: (contact with no FirstName and Phone is null)
Output: ['Johnson']
Explanation: When FirstName is null, only LastName is returned
