DSA #5 | Math and Recursion | Count Digits and Reverse Number

DSA Phase-1 Math and Recursion tutorial. In this video you will learn basic math and recursion problems that are very important for building logic in DSA and cracking interviews. We will cover how to count digits in a number and how to reverse a number using clear logic, dry run, and clean code. Time and space complexity along with interview use cases are also explained. Topics covered in this video: --Introduction to Math and Recursion --Count digits in a number --Reverse a number --Logic and dry run explanation --Recursive and iterative approach --Time complexity analysis --Space complexity analysis --Interview use cases This video is useful for DSA beginners, students, freshers, and interview preparation. ⏱️ Key Video Timestamps :- 00:35 –Count Digits & Reverse Number 07:01 – Reverse Number problem introduced 07:47 – “Golden Rule” for reversing a number 09:39 – Reverse number code logic starts 10:38 – Reverse number dry run 12:19 – Time & Space Complexity ⚙️ Tech Used JavaScript, VS Code and Terminal 📂 Playlist Links: JavaScript Full Course Video (Hindi):    • JavaScript Full Course 2025  | 4 Projects ...   React 19 Full Course Video (Hindi):    • ReactJS Full Course in Hindi – Beginner to...   Angular 21 Full Course Video (Hindi):    • Angular 21 Full Course in Hindi (2026) | B...   Python Full Course Video (Hindi):    • Python Full Course in Hindi 2025 | Complet...   Django Full Course Video (Hindi):    • Django Tutorial in Hindi 2026 | Complete D...   NodeJS Full Course Video (Hindi):    • Complete Node.js + Express.js + MongoDB Co...   Git and GitHib Copilot Full Course Video (Hindi):    • GitHub Copilot Full Course in 1 Video | Gi...   🔗 Follow Me for Updates: TopMate:[Connect with Me](https://topmate.io/mohitdecodes) WhatsApp:[Connect with Me](https://whatsapp.com/channel/0029Vb6C...)
