This question runs in a pre-configured Salesforce environment - no personal connection required.
Query all Prospect accounts and reclassify them as Customer if their AnnualRevenue is greater than or equal to a given threshold. Update the matching accounts in bulk and return the number of records updated. Return 0 if no accounts match the threshold. Return 0 for null or negative threshold values.
Method Signature: public static Integer consolidateAccountTypes(Decimal revenueThreshold)
Examples:
Input: revenueThreshold = 999999999
Output: 0
Explanation: No Prospect accounts have revenue that high, so no updates occur
Input: revenueThreshold = null
Output: 0
Explanation: Null threshold is invalid, return 0 immediately
Input: revenueThreshold = -100
Output: 0
Explanation: Negative threshold is invalid, return 0 immediately
Input: revenueThreshold = 0
Output: (count of Prospect accounts with non-null AnnualRevenue)
Explanation: All Prospect accounts with a defined revenue qualify at threshold 0
