How Heaps Power Priority-Based Decision Making in Software Systems

A Heap is a data structure optimized for continuous decision-making, keeping the most important element immediately accessible at all times. Unlike a HashMap, which retrieves a known object, a Heap repeatedly answers questions like 'what should happen next?' based on defined priorities. Real-world applications include CPU scheduling, ride-assignment platforms, hospital triage systems, and support ticket routing. Heaps come in two forms: a Max Heap prioritizes the largest value, while a Min Heap surfaces the smallest, such as the earliest deadline or cheapest route. The business logic determines what 'most important' means, while the Heap ensures that element is always ready to be acted upon.
