    Given a binary fraud pattern where each bit represents a specific fraud indicator (0 for normal, 1 for suspicious activity), write a function that identifies and flags the leftmost unflagged fraud indicator in the pattern. This modification helps enhance the bank's fraud detection system by ensuring no potential fraud indicators are overlooked in the analysis process.
