Advanced Data Structures in C# (Part 1): Stacks Explained for Unity & Game Dev

Welcome to Part 1 of our deep dive into advanced data structures in C#! In this video, we explore the foundational concepts and practical applications of Stacks, Queues, and HashSets. These structures are essential tools in a developer's arsenal, enabling efficient data management and problem-solving strategies.

Topics Covered:

Understanding Stacks (LIFO - Last In, First Out):

Purpose & Use Cases: Ideal for scenarios like undo mechanisms, expression evaluation, and backtracking algorithms.

Key Operations:

Push: Add an element to the top.

Pop: Remove the top element.

Peek: View the top element without removing it.

C# Implementation: Utilizing Stack from the System.Collections.Generic namespace for type safety and performance.

Exploring Queues (FIFO - First In, First Out):

Purpose & Use Cases: Suitable for task scheduling, breadth-first search algorithms, and buffering data streams.

Key Operations:

Enqueue: Add an element to the end.

Dequeue: Remove the element from the front.

Peek: Inspect the front element without removing it.

C# Implementation: Leveraging Queue for efficient FIFO operations.

Delving into HashSets:

Purpose & Use Cases: Ensures uniqueness of elements, making it perfect for managing collections like user IDs or ensuring no duplicates in a dataset.

Key Characteristics:

Unordered collection of unique elements.

Fast operations for add, delete, and lookup.

C# Implementation: Using HashSet to efficiently manage unique data entries.

Practical Applications:

Stacks: Implementing undo features in applications, parsing expressions, and navigating through application states.

Queues: Managing print jobs, handling asynchronous data processing, and implementing producer-consumer scenarios.

HashSets: Maintaining a collection of unique items, such as tracking visited nodes in a graph or ensuring unique entries in a dataset.
