DSA in C# | Data Structure and Algorithm using C#

  DSA in C# |  Data Structure and Algorithm using C#: Lecture 1: Introduction to Data Structures and Algorithms (1 Hour) 1.1 What are Data Structures? Data Structures are ways to store and organize data so it can be used efficiently. Think of data structures as containers that hold data in a specific format. Types of Data Structures: Primitive Data Structures : These are basic structures built into the language. Example: int , float , char , bool in C#. Example : csharp int age = 25;  // 'age' stores an integer value. bool isStudent = true;  // 'isStudent' stores a boolean value. Non-Primitive Data Structures : These are more complex and are built using primitive types. They are divided into: Linear : Arrays, Lists, Queues, Stacks (data is arranged in a sequence). Non-Linear : Trees, Graphs (data is connected in more complex ways). Example : // Array is a simple linear data structure int[] number...
