    In a busy emergency room's resource management system, develop a function that identifies and activates the highest-priority inactive medical resource when needed. Given a binary status number where 1 represents an active resource and 0 represents an inactive resource, the function should locate and activate (change to 1) the leftmost inactive resource (0) in the sequence. This optimization ensures that critical medical resources are allocated in order of priority during peak hours.
