Static variables are shared among all instances of a class, while non-static variables belong to individual instances.
Static variables are declared using the 'static' keyword, while non-static variables are not.
Static variables are initialized only once at the start of the program, while non-static variables are initialized each time an instance is created.
Static variables can be accessed using the class name, while no...

A pipeline is a series of interconnected steps or stages in a process, where output of one step is input to the next step.
Pipeline is commonly used in software development for continuous integration and continuous delivery processes.
Each step in the pipeline performs a specific task, such as building, testing, and deploying code.
Pipeline automation tools like Jenkins, GitLab CI/CD, and Azure DevOps help in managing and
The .NET Framework is a software framework developed by Microsoft that provides a large library of pre-coded solutions to common programming problems.
Developed by Microsoft
Provides a large library of pre-coded solutions
Supports multiple programming languages like C#, VB.NET, F#
Consists of Common Language Runtime (CLR) and Framework Class Library (FCL)
The different components of DOT-NET include Common Language Runtime (CLR), Framework Class Library (FCL), and ASP.NET.
Common Language Runtime (CLR) - provides various services such as memory management, exception handling, and security.
Framework Class Library (FCL) - a collection of reusable classes, interfaces, and value types that provide access to system functionality.

Abstract classes can have implementation details while interfaces cannot.
Abstract classes can have method implementations while interfaces cannot.
A class can inherit only one abstract class but can implement multiple interfaces.
Abstract classes can have access modifiers on their members while interfaces cannot.
Interfaces are used to define a contract for classes to implement.
Abstract classes are used to provide a commo

Method overloading is when multiple methods in a class have the same name but different parameters.
Allows multiple methods with the same name but different parameters to be defined in a class
Parameters can differ in number, type, or order
Example: void print(int num) and void print(String text) are overloaded methods
Method overriding is a feature in object-oriented programming that allows a subclass to provide a specific implementation of a method that is already provided by its superclass.
Method overriding is done when a subclass provides a specific implementation for a method that is already defined in its superclass.
The method in the subclass must have the same name, return type, and parameters as the method in the superclass.

A singleton class is a class that can only have one instance created and provides a global point of access to that instance.
Singleton classes are often used for logging, caching, database connections, and thread pools.
They typically have a private constructor to prevent instantiation from outside the class.
The class itself usually provides a static method to access the single instance.
Oops Pillars are the four main concepts of Object-Oriented Programming: Inheritance, Encapsulation, Polymorphism, and Abstraction.
Inheritance: Allows a class to inherit properties and behavior from another class.
Encapsulation: Bundles data and methods into a single unit, protecting data from outside interference.
Polymorphism: Allows objects to be treated as instances of their parent class, enabling flexibility in code.

Dependency injection is a design pattern in which components are given their dependencies rather than creating them internally.
Allows for easier testing by mocking dependencies
Promotes loose coupling between components
Improves code reusability and maintainability
Examples: Constructor injection, Setter injection, Interface injection

Find the single number in a sorted array with frequency of 2 for all other numbers.
Use binary search to find the number with different frequency.
Check if the mid element is at even or odd index to determine which side to search next.
Example: Input array [1, 1, 2, 2, 3, 3, 4, 4, 5] should return 5.
Print the left view of a tree by traversing the tree from left to right at each level
Traverse the tree using level order traversal
Print the first node at each level encountered during traversal
