Updating Salesforce Logs Problem Description In a Salesforce environment, optimize the customer interaction logging service by transforming the service's data structure. Optimize the interaction log by repeatedly updating the entries based on a specific transformation logic. This optimization will enhance the service's ability to efficiently retrieve and process historical customer data. The log is updated according to the following steps: The process is driven by a loop that runs from i = 0 to iterations - 1 . In each step of the loop, two indices are calculated: i1 = i % n (current position), where n is the size of the log. i2 = n - 1 - (i % n) (symmetric position). The log entry at index i1 is updated using the bitwise XOR operation: log[i1] = log[i1] ^ log[i2] . After all iterations are complete, the final updated log array is returned. Example Suppose n = 4 , log = [5, 6, 7, 8] , and iterations = 3 . i i1 i2 log[i1] log[i2] XOR log' (updated log) (initial) - - - - - [5, 6, 7, 8] 0
