priority queues

Priority queues are abstract data structures that store elements with associated priorities. They follow the rule that elements with higher priorities are dequeued before elements with lower priorities. This allows priority queues to efficiently retrieve the highest-priority element from a collection. The implementation of priority queues may vary, but they typically provide operations like inserting an element, removing the highest-priority element, and accessing the highest-priority element without removing it. Priority queues are often used in algorithms and applications where ordering elements based on their priorities is crucial, such as in scheduling, resource allocation, and graph algorithms.
