Max heap priority queue
Web26 aug. 2016 · In this chapter, we consider several classical sorting methods and an efficient implementation of a fundamental data type known as the priority queue. We discuss the theoretical basis for comparing sorting algorithms and conclude the chapter with a survey of applications of sorting and priority-queue algorithms. WebPriorityQueue A priority queue is an abstract data type. We do not specify the implementation when it is abstract. Heap A binary heap is not an abstract data type; it is …
