โœ… Step-by-Step Approach to Learn Programming ๐Ÿ’ป๐Ÿš€

โžŠ Pick a Programming Language
Start with beginner-friendly languages that are widely used and have lots of resources.
โœ” Python โ€“ Great for beginners, versatile (web, data, automation)
โœ” JavaScript โ€“ Perfect for web development
โœ” C++ / Java โ€“ Ideal if you're targeting DSA or competitive programming
Goal: Be comfortable with syntax, writing small programs, and using an IDE.

โž‹ Learn Basic Programming Concepts
Understand the foundational building blocks of coding:
โœ” Variables, data types
โœ” Input/output
โœ” Loops (for, while)
โœ” Conditional statements (if/else)
โœ” Functions and scope
โœ” Error handling
Tip: Use visual platforms like W3Schools, freeCodeCamp, or Sololearn.

โžŒ Understand Data Structures & Algorithms (DSA)
โœ” Arrays, Strings
โœ” Linked Lists, Stacks, Queues
โœ” Hash Maps, Sets
โœ” Trees, Graphs
โœ” Sorting & Searching
โœ” Recursion, Greedy, Backtracking
โœ” Dynamic Programming
Use GeeksforGeeks, NeetCode, or Striver's DSA Sheet.

โž Practice Problem Solving Daily
โœ” LeetCode (real interview Qs)
โœ” HackerRank (step-by-step)
โœ” Codeforces / AtCoder (competitive)
Goal: Focus on logic, not just solutions.

โžŽ Build Mini Projects
โœ” Calculator
โœ” To-do list app
โœ” Weather app (using APIs)
โœ” Quiz app
โœ” Rock-paper-scissors game
Projects solidify your concepts.

โž Learn Git & GitHub
โœ” Initialize a repo
โœ” Commit & push code
โœ” Branch and merge
โœ” Host projects on GitHub
Must-have for collaboration.

โž Learn Web Development Basics
โœ” HTML โ€“ Structure
โœ” CSS โ€“ Styling
โœ” JavaScript โ€“ Interactivity
Then explore:
โœ” React.js
โœ” Node.js + Express
โœ” MongoDB / MySQL

โž‘ Choose Your Career Path
โœ” Web Dev (Frontend, Backend, Full Stack)
โœ” App Dev (Flutter, Android)
โœ” Data Science / ML
โœ” DevOps / Cloud (AWS, Docker)

โž’ Work on Real Projects & Internships
โœ” Build a portfolio
โœ” Clone real apps (Netflix UI, Amazon clone)
โœ” Join hackathons
โœ” Freelance or open source
โœ” Apply for internships

โž“ Stay Updated & Keep Improving
โœ” Follow GitHub trends
โœ” Dev YouTube channels (Fireship, etc.)
โœ” Tech blogs (Dev.to, Medium)
โœ” Communities (Discord, Reddit, X)

๐ŸŽฏ Remember:
โ€ข Consistency > Intensity
โ€ข Learn by building
โ€ข Debugging is learning
โ€ข Track progress weekly

๐Ÿ“š Top 10 HTML Interview Questions With Answers

1. What is HTML? 
   HTML (HyperText Markup Language) is the standard language used to create and design web pages. It structures content by using elements and tags.

2. What are the different types of HTML tags? 
   There are block-level tags (like <div>, <p>, <h1>) which start on a new line, and inline tags (like <span>, <a>, <img>) which do not start on a new line.

3. What is the difference between HTML elements and tags? 
   A tag is the markup itself (e.g., <p>), while an element includes the opening tag, content, and closing tag (<p>Content</p>).

4. What are semantic HTML elements? 
   Semantic elements clearly describe their meaning in a human- and machine-readable way. Examples include <header>, <footer>, <article>, and <section>.

5. What is the purpose of the doctype declaration in HTML? 
   The <!DOCTYPE html> declaration defines the document type and version of HTML, helping browsers render the page correctly.

6. What are the different ways to include CSS in an HTML page? 
   CSS can be added via inline styles (style attribute), internal styles (<style> tag inside <head>), or external style sheets linked via <link> tag.

7. What is the difference between an ID and a Class in HTML? 
   ID is unique within a page and is used to identify a single element, while class can be assigned to multiple elements for styling or scripting.

8. How do you create a hyperlink in HTML? 
   Using the <a> tag with an href attribute, e.g., <a href="https://example.com">Link</a>.

9. What are HTML forms used for? 
   Forms collect user input and submit data to a server for processing, with tags like <form>, <input>, <textarea>, <button>, and more.

10. What is the role of the <meta> tag in HTML? 
    Meta tags provide metadata about the HTML document such as character set, page description, viewport settings, and SEO info.

2. SELECT e1.* FROM employees e1 JOIN employees e2 ON e1.manager_id = (link unavailable) WHERE e1.salary > e2.salary

3. SELECT * FROM table WHERE rowid IN (SELECT rowid FROM table GROUP BY column HAVING COUNT(*) > 1)

4. SELECT * FROM table WHERE salary > (SELECT PERCENTILE_CONT(0.9) WITHIN GROUP (ORDER BY salary) FROM table)

5. SELECT column, SUM(column) OVER (ORDER BY rowid) FROM table

6. SELECT * FROM employees WHERE id NOT IN (SELECT employee_id FROM leaves)

7. SELECT *, column - LEAD(column) OVER (ORDER BY rowid) FROM table
