Priority queue

In computer science, a priority queue is an abstract data type similar to a regular queue where each element has an associated priority determining its order of service. Priority queue serves highest priority items first. Priority values have to be instances of an ordered data type, and higher priority can be given either to the lesser or to the greater…
