Using Priority Queues in C#

Priority queues are data structures that store elements based on their priority. The highest-priority item is always available for immediate access. C#'s `PriorityQueue` class (available in .NET 6 and later) makes working with priority queues straightforward.

Understanding Priority Queues

A priority queue organizes elements according to a priority key. The element with the highest priority is processed first. The priority can be any comparable type (integer, string, etc.).

The `PriorityQueue` Class

The `PriorityQueue` class is a generic class, meaning you specify the type of the elements (`TElement`) and their priority keys (`TPriority`). The priority key determines the order of elements in the queue.

Example: Managing Tasks by Priority

using System;
using System.Collections.Generic;

public class Task : IComparable<Task> {
    // ... (Task class with Name and Priority properties, and CompareTo method) ...
}

public class PriorityQueueExample {
    public static void Main(string[] args) {
        // ... (code to create PriorityQueue, enqueue tasks, and dequeue tasks) ...
    }
}
