This question runs in a pre-configured Salesforce environment - no personal connection required.
Write a method that uses SOQL to group Account records by their Rating and return a Map where the key is the Rating and the value is a List of Account records with that rating.
Examples:
Input: Database with accounts having different ratings
Output: Map<String, List<Account>>
{
'Hot' => [Account1, Account2, Account3],
'Warm' => [Account4, Account5],
'Cold' => [Account6]
}
Example Processing:
- Accounts with Rating = 'Hot': 15 accounts
- Accounts with Rating = 'Warm': 11 accounts
- Accounts with Rating = 'Cold': 4 accounts
- Accounts with Rating = null: grouped under null key
