Проблема: стандартные массивы для очереди могут привести к необходимости дорогостоящих операций сдвига элементов при удалении.
Решение: в книге Algorithms and Data Structures for OOP With C# автор предлагает реализовать очередь на основе связного списка, что позволяет эффективно добавлять элементы в конец и удалять с начала за O(1).
Пример кода:
public class Node<T> { public T Data; public Node<T> Next;
public Node(T data) { Data = data; Next = null; } }
public class QueueLinkedList<T> { private Node<T> front, rear;
public QueueLinkedList() { front = rear = null; }
public void Enqueue(T item) { var newNode = new Node<T>(item); if (rear == null) { front = rear = newNode; return; } rear.Next = newNode; rear = newNode; }
public T Dequeue() { if (front == null) throw new InvalidOperationException("Queue is empty.");
var data = front.Data; front = front.Next;
if (front == null) rear = null;
return data; } }
Преимущества: — Нет затрат на сдвиг элементов — Высокая производительность при операциях добавления и удаления — Универсальная реализация для любых типов данных

Telegram today rolling out an update which brings with it several new features.The update also adds interactive emoji. When you send one of the select animated emoji in chat, you can now tap on it to initiate a full screen animation. The update also adds interactive emoji. When you send one of the select animated emoji in chat, you can now tap on it to initiate a full screen animation. This is then visible to you or anyone else who's also present in chat at the moment. The animations are also accompanied by vibrations. This is then visible to you or anyone else who's also present in chat at the moment. The animations are also accompanied by vibrations.
That strategy is the acquisition of a value-priced company by a growth company. Using the growth company's higher-priced stock for the acquisition can produce outsized revenue and earnings growth. Even better is the use of cash, particularly in a growth period when financial aggressiveness is accepted and even positively viewed.he key public rationale behind this strategy is synergy - the 1+1=3 view. In many cases, synergy does occur and is valuable. However, in other cases, particularly as the strategy gains popularity, it doesn't. Joining two different organizations, workforces and cultures is a challenge. Simply putting two separate organizations together necessarily creates disruptions and conflicts that can undermine both operations.
