    Given a sequence of parking space occupancy data where '1' represents an occupied spot and '0' represents a vacant spot, find the parking zone segment with the maximum difference between vacant and occupied spaces. The solution will help identify the most underutilized or congested sections of the parking zone to optimize space allocation and guide drivers efficiently.
