This question runs in a pre-configured Salesforce environment - no personal connection required.

Write a method that uses SOQL to find all Account names where the Phone field is null or empty. This is useful for data quality checks to identify accounts missing contact information. Return the names ordered alphabetically. Return an empty list if all accounts have phone numbers.

Examples:

Input: None (method queries all accounts) Output: ['Account A', 'Account B', 'Account C', ...] Explanation: Returns all account names where Phone is null, sorted A-Z Input: If all accounts have phone numbers Output: [] Explanation: Returns empty list when no accounts match criteria
