Prompt engineering, sadharan shabdo mein, Large Language Models (LLMs) jaise GPT-4, Claude, aur Gemini se behtarin (best) output paane ke liye sahi input (prompt) likhne ki kala hai. Ismein yah samajhna zaroori hai ki model aapke instructions ko kaise samajhta hai aur apne sawalon ko is tarah se structure karna ki aapko sahi, relevant aur consistent jawab mile.

As AI tools become integral to software development, prompt engineering is becoming a critical skill for developers.

1. What is GitHub Copilot?

A coding assistant that suggests whole lines or blocks of code as you type. It’s like an autocomplete on steroids. It understands context from comments and function names to generate relevant code. Example: Type // function to calculate average and it writes the function body for you.

2. What is ChatGPT?

A conversational AI that can answer questions, write code, explain concepts, and even debug your errors. It acts like a pair programmer, helping you brainstorm logic or convert code from one language to another. Example: Paste a Python script and ask, “Convert this to JavaScript,” and it generates the JS version.

1. What is Artificial Intelligence (AI)?

Making computers smart so they can think and learn like humans. Examples: Recognizing faces, driving cars, or playing chess.

2. What are the different types of AI?

• Weak AI (Narrow AI): Good at one specific job (e.g., Siri, Alexa, playing Chess).
• Strong AI (General AI): Smart like a human (can handle any task). Does not exist yet.
• Super AI: Smarter than humans (Sci-fi movie stuff).

3. What is the difference between AI, Machine Learning (ML), and Deep Learning (DL)? Think of Russian dolls:

1. What is an algorithm?

Simple steps to solve a problem. Think of it like a recipe for cooking: step 1, step 2, step 3 to get the result.

2. Explain the difference between linear search and binary search.

• Linear Search: Checking items one by one, like reading every page of a book to find a word. Works on any list.
• Binary Search: Only works on sorted lists. You open the book in the middle; if the word is before, you ignore the second half and repeat. It cuts the search area in half every time.

3. What is the time complexity of linear search and binary search?

       When it comes to developing applications using Spring Boot, there are several annotations that are commonly used. Here are some of the most frequently used annotations in Spring Boot:

       1. @RestController

       The @RestController annotation is used to define a class as a RESTful controller. It combines the @Controller and @ResponseBody annotations, making it easier to create RESTful APIs.

       2. @RequestMapping

       The @RequestMapping annotation is used to map HTTP requests to specific controller methods. It allows you to define the URL path and HTTP method for handling the requests.

       SOLID Design Principles

       SOLID is an acronym that represents a set of five design principles aimed at improving software design and maintainability. Here’s a brief description of each principle:

       1. Single Responsibility Principle (SRP)

       • A class should have only one reason to change.
       • It states that a class should have a single responsibility and should be focused on doing one thing well.
       • This principle promotes modularity and makes classes easier to understand, test, and maintain.

       2. Open/Closed Principle (OCP)

       • Software entities (classes, modules, functions) should be open for extension but closed for modification.
       • It suggests that code should be written in a way that new functionality can be added without modifying existing code.
       • This principle promotes code reusability, maintainability, and allows for easier integration of new features.

       3. Liskov Substitution Principle (LSP)

       • Subtypes must be substitutable for their base types.
       • It ensures that objects of a superclass can be replaced with objects of its subclass without affecting the correctness of the program.
       • This principle promotes code reuse and helps maintain a consistent and predictable behavior of objects in a hierarchy.

       4. Interface Segregation Principle (ISP)

       • Clients should not be forced to depend on interfaces they do not use.
       • It suggests that interfaces should be fine-grained and focused on specific client requirements.
       • This principle promotes decoupling, modularity, and prevents the problem of “fat” interfaces.

       5. Dependency Inversion Principle (DIP)

       • High-level modules should not depend on low-level modules; both should depend on abstractions.
       • It states that the dependency should be on abstractions rather than concrete implementations.
       • This principle promotes loose coupling, flexibility, and facilitates easier unit testing and modular design.

          1. What are the main advantages of using microservices architecture?

          Microservices architecture provides benefits such as improved scalability, fault isolation, independent deployment, technology diversity, and better team autonomy.

          2. How do microservices communicate with each other?

          Microservices typically communicate through lightweight protocols such as HTTP/REST or messaging systems like RabbitMQ or Apache Kafka. API gateways and service registries can also be used for service discovery and communication.

          1. What is REST?

          REST (Representational State Transfer) is an architectural style for designing networked applications. It relies on the HTTP protocol and emphasizes stateless, client-server communication through standard CRUD operations (Create, Read, Update, Delete).

          2. What is a RESTful web service?

          A RESTful web service is an implementation of the REST architecture that allows clients to interact with resources over the web using HTTP methods like GET, POST, PUT, and DELETE. It follows the principles of statelessness, uniform resource identification, and representation.

          1. What is Spring Boot?

          Spring Boot is a Java framework that simplifies the development of Java applications by providing default configurations, dependency management, and production-ready features out of the box.

          2. Explain the key features of Spring Boot.

          • Auto-configuration: Spring Boot automatically configures application components based on classpath settings and dependencies.
          • Starter dependencies: Spring Boot provides a set of curated dependencies that are commonly used together for specific functionalities.
          • Embedded server: Spring Boot comes with an embedded server (e.g., Tomcat, Jetty) that eliminates the need for deploying applications to a separate server.
          • Actuator: It provides production-ready features like health checks, metrics, and monitoring for applications.
          • Spring Boot CLI: Spring Boot Command Line Interface allows rapid prototyping and development using Groovy scripts.

          3. How does Spring Boot differ from the Spring Framework?

          Spring Boot builds on top of the Spring Framework and aims to simplify the configuration and setup process.
