Harshad Number Program in Java | TCS NQT Ninja Prime Coding Question | Step-by-Step Solution

🔢 Master Harshad Number Program for TCS NQT, Ninja & Prime Exams | Complete Coding Tutorial with Algorithm, Dry Run & Complexity Analysis Welcome to Infotechiezz! In this comprehensive tutorial, we break down the Harshad Number (Niven Number) problem – one of the most frequently asked coding questions in TCS NQT, TCS Ninja, and TCS Prime recruitment drives. Whether you're a beginner or an experienced coder preparing for campus placements, this step-by-step guide will help you understand, implement, and optimize the Harshad Number logic with confidence. ✅ What You'll Learn in This Video/Blog: 🔹 0:00 – Introduction to Harshad Numbers: 🔹 2:08 – Real Examples of Harshad Numbers: 🔹 2:58 – Non-Harshad Number Cases: 🔹 3:25 – Algorithm Design: 🔹 4:10 – Pseudo Code Walkthrough: 🔹 5:42 – Full Coding Implementation: 🔹 9:06 – Dry Run with Example: 🔹 10:45 – Time & Space Complexity Analysis: 🔹 11:13 – Real-World Applications & Interview Tips: 🔹 12:37 – Practice Questions for TCS NQT 🔹 13:37 – Outro 🎯 Why This Matters for TCS Aspirants: The Harshad Number problem tests core programming fundamentals – loops, conditionals, arithmetic operations, and function design – all critical for TCS NQT coding sections. Mastering this pattern helps you solve similar digit-manipulation problems like Armstrong Number, Palindrome Check, Digital Root, and Sum of Digits recursively. 💡 Pro Tips for Exam Success: ✔️ Always handle edge cases: n=0, negative inputs, single-digit numbers ✔️ Prefer mathematical approach over string conversion for better performance ✔️ Practice writing clean, commented code – TCS evaluators value readability ✔️ Memorize the complexity justification – often asked in technical interviews ✔️ Use modular functions for reusability in multi-part questions 📚 Resources Mentioned: • Free Harshad Number Code Template (GitHub Link in Description) • TCS NQT Previous Year Question Bank (PDF Download) • Digit-Sum Problem Practice Sheet (Google Drive) • Infotechiezz Discord Community for Doubt Solving 🔔 Don't Forget to: ✅ Like this video if it helped you ✅ Subscribe to @infotechiezz for daily coding content ✅ Hit the bell icon for instant updates on TCS preparation series ✅ Share with friends preparing for placements harshad number program, niven number explained, tcs nqt coding questions 2026, tcs ninja coding problems, tcs prime coding questions, check harshad number in c++, harshad number java code, python harshad number solution, digit sum divisibility problem, placement coding preparation, campus placement coding questions, tcs nqt previous year questions, harshad number algorithm, pseudo code for harshad number, dry run coding example, time complexity analysis coding, space complexity optimization, tcs coding round tips, infotechiezz coding tutorial, harshad number practice problems, number theory coding questions, modulo operator programming, digit extraction technique, competitive programming basics, beginner coding tutorial, tcs interview preparation, nqt coding solutions, harshad number edge cases, coding interview questions india, infotechiezz youtube channel #️⃣ HASHTAGS: #HarshadNumber #NivenNumber #TCSNQT #TCSNinja #TCSPrime #CodingInterview #PlacementPreparation #CampusPlacement #CPlusPlus #JavaProgramming #PythonCoding #AlgorithmDesign #DryRun #ComplexityAnalysis #DigitSum #ModuloOperator #CompetitiveProgramming #Infotechiezz #CodingTutorial #Placement2026 #TCSRecruitment #CodingQuestions #ProgrammingLogic #CodeWithInfotechiezz #TechEducation #LearnToCode #CodingForBeginners #InterviewPrep #CodingPractice #NumberTheory #CodingShorts #ProgrammingTips #TechCommunity #CodeNewbie #PlacementReady #TCSOffCampus #CodingChallenge #ProblemSolving #DeveloperCommunity #CodeDaily 📲 CONNECT WITH INFOTECHIEZZ: 📩 Email: [email protected] 📸 Instagram: https://www.instagram.com/infotechiezz/ 💼 LinkedIn: https://www.linkedin.com/in/infotechiezz/ ▶️ YouTube: https://www.youtube.com/@InfoTechiezz 💬 WhatsApp Channel: https://www.whatsapp.com/channel/0029Vb7QJZG8fewpER7N8U0V 🐦 X (Twitter): https://x.com/infotechiezz 🔢 Quick Harshad Number Logic: A Harshad Number is divisible by the sum of its digits. Example: 18 → 1+8=9 → 18%9=0 ✓ Harshad Example: 15 → 1+5=6 → 15%6=3 ✗ Not Harshad ⚠️ Disclaimer: This content is for educational purposes.
