Two possible solutions:
1. Separated queue for every possible priority value.
2. One shared queue for every elements, sorted by priority.
Separated queue for every possible priority value.
These are completely unrelated things.
Yes it is possible to implement stack and queue using linked list
algorithm on multiple queues in a single dimensional array
A binary heap is a complete binary tree that satisfies the heap property, where the parent node is either greater than or less than its children. It is typically used to implement priority queues efficiently. On the other hand, a binary tree is a hierarchical data structure where each node has at most two children. While both structures are binary, a binary heap is specifically designed for efficient insertion and deletion of elements based on their priority, while a binary tree can be used for various purposes beyond just priority queues.
Priority queues can be found in operating systems for load-balancing and interrupt handling, network servers for bandwidth management, compression algorithms (such as Huffman encoding), Dijkstra's algorithm, Prim's algorithm and artificial intelligence systems.
A heap is a specialized tree-based data structure in computer science that is used to efficiently store and manage a collection of elements. It is commonly used to implement priority queues, where elements are stored in a way that allows for quick retrieval of the highest (or lowest) priority element. Heaps are also used in algorithms like heap sort and Dijkstra's shortest path algorithm.
A queue in any language is a singly-linked list structure that permits new data to be inserted only at the end of a list while existing data can only be extracted from the beginning of the list. Queues are also known as a first in, first out (FIFO) structure. Unlike a standard singly-linked list, the list maintains a pointer to the last node as well as the first, in order to insert new data and extract existing data in constant time. Variations on the queue include the priority queue which permit data to be weighted, such that data with the greatest priority is promoted to the front of the queue, behind any existing data with the same or higher priority, using an insertion sort technique. Insertion is therefore achieved in linear time rather than constant time, however extraction is always in constant time.

This chapter presents two ADTs: Queues and Priority Queues. In real life a queue is a line of customers waiting for service of some kind. In most cases, the first customer in line is the next customer to be served. There are exceptions, though. For example, at airports customers whose flight is leaving imminently are sometimes taken from the middle of the queue. Also, at supermarkets a polite customer might let someone with only a few items go first.The rule that determines who goes next is called a queueing discipline. The simplest queueing discipline is called FIFO, for "first-in-first-out." The most general queueing discipline is priority queueing, in which each customer is assigned a priority, and the customer with the highest priority goes first, regardless of the order of arrival. The reason I say this is the most general discipline is that the priority can be based on anything: what time a flight leaves, how many groceries the customer has, or how important the customer is. Of course, not all queueing disciplines are "fair," but fairness is in the eye of the beholder.The Queue ADT and the Priority Queue ADT have the same set of operations and their interfaces are the same. The difference is in the semantics of the operations: a Queue uses the FIFO policy, and a Priority Queue (as the name suggests) uses the priority queueing policy.As with most ADTs, there are a number of ways to implement queues Since a queue is a collection of items, we can use any of the basic mechanisms for storing collections: arrays, lists, or vectors. Our choice among them will be based in part on their performance--- how long it takes to perform the operations we want to perform--- and partly on ease of implemen
Queues is the plural of queue.
