Clean architecture principles focus on separation of concerns, independence of frameworks, testability, and maintainability.
Separation of concerns: Dividing the application into layers (e.g. presentation, domain, data) to ensure each layer has a specific responsibility.
Independence of frameworks: Decoupling the application from external frameworks to make it easier to switch or update frameworks in the future.
Testabili...

Using sliding window technique to find subarray with sum equal to k.
Initialize two pointers at the start of the array.
Move the right pointer to expand the window until the sum is greater than or equal to k.
Move the left pointer to shrink the window if the sum exceeds k.
Repeat until the end of the array is reached.
Example: Input array [1, 4, 20, 3, 10, 5], k=33. Output: [20, 3, 10].

A singleton class is a class that can only have one instance created throughout the application.
Singleton classes are often used for logging, caching, database connections, and thread pools.
They have a private constructor to prevent multiple instances from being created.
The class typically provides a static method to access the single instance.
Method reference is a shorthand syntax for lambda expressions to call a method.
Method reference is used to refer to a method without invoking it.
It can be used to make code more concise and readable.
There are four types of method references: static, instance, constructor, and array constructor.

Polymorphism: Ability to present the same interface for different data types.
Abstraction: Hiding the complex implementation details and showing only the ne
SOLID principles are a set of five design principles that help developers create more maintainable and scalable software.
Single Responsibility Principle (SRP) - A class should have only one reason to change.
Open/Closed Principle (OCP) - Software entities should be open for extension but closed for modification.
Liskov Substitution Principle (LSP) - Objects of a superclass should be replaceable with objects of its subcla...
