A priority queue is a versatile data structure that is good to have under your algorithmic toolbelt. In this post, we discuss, what it is, real-world applications, and we explore two different implementations, the latter one being more robust....
Before studying the priority queue, please refer to the heap data structure for a better understanding of binary heap as it is used to implement the priority queue in this article. 1. Inserting an Element into the Priority Queue Inserting an element into a priority queue (max-heap) is done...
There is a need to have a simple data structure that can be used as a priority queue with low overhead. The data structure should have the operation where the data item with the minimum/maximum value is the next item to be deleted. The data structure should also support the function of...
Definition & Description: Incomputer science/data structures, apriority queueis anabstract data typewhich is like a regularqueueorstackdata structure, but where additionally each element has a "priority" associated with it. In a priority queue, an element with high priority is served before an el...
Priority Queue A priority queue is a data structure which maintains a setSS of elements, each of with an associated value (key), and supports the following operations: insert(S,k)insert(S,k): insert an elementkk into the setSS extractMax(S)extractMax(S): remove and return the element ...

A priority queue (PQ) supports two operations: insert and deleteMin. The abstract definition of a PQ provides a set of key-value pairs, where the key represents a priority. The insert() method inserts a new key-value pair into the set (the keys don't have to be unique), and the ...
