This question runs in a pre-configured Salesforce environment - no personal connection required.
Write a method that uses SOQL to find all Industry and BillingCountry combinations where more than one Account exists. Return a List<String> where each entry is formatted as 'Industry - Country (count)' and sorted alphabetically by the formatted string. Return an empty list if no combinations have more than one account.
Examples:
Input: Database contains 3 accounts with Industry='Technology' and BillingCountry='USA'
Output: ['Technology - USA (3)']
Explanation: The combination has 3 accounts, so it is included
Input: Database contains 2 accounts with Industry='Finance' and BillingCountry='UK',
and 2 accounts with Industry='Healthcare' and BillingCountry='Canada'
Output: ['Finance - UK (2)', 'Healthcare - Canada (2)']
Explanation: Both combinations have more than one account, sorted alphabetically
Input: Database contains 1 account with Industry='Manufacturing' and BillingCountry='Germany'
Output: []
Explanation: The combination has only 1 account, so it is excluded
Input: Database contains 2 accounts with Industry='Technology' and BillingCountry='Japan',
and 1 account with Industry='Technology' and BillingCountry='USA'
Output: ['Technology - Japan (2)']
Explanation: Only the Japan combination has more than one account
Input: No accounts in database
Output: []
