Rotate Matrix by 90 Degree in Java |BHARAT TECH SHOW

🔥 Welcome to Bharat Tech Show 🔥 In this video, we will solve an important 2D Array problem: ============================== 📌 PROBLEM STATEMENT ============================== Given a square matrix of size N × N, rotate the matrix by 90 degrees clockwise without using extra space. You must perform the rotation in-place. ============================== 📌 INPUT FORMAT ============================== First line: Two integers N and M (number of rows and columns) Next N lines: M integers representing the matrix elements. Example Input: 3 3 1 2 3 4 5 6 7 8 9 ============================== 📌 OUTPUT FORMAT ============================== Print the matrix after rotating it by 90 degrees clockwise. Example Output: 7 4 1 8 5 2 9 6 3 ============================== 💡 LOGIC USED ============================== Step 1: Transpose the matrix Step 2: Reverse each row Transpose + Reverse = 90° Clockwise Rotation ============================== 🎯 Why This Question is Important? ============================== ✔ Frequently asked in coding interviews ✔ Important for DSA preparation ✔ Builds strong 2D Array concepts ✔ Asked in college exams & placements -------------------------------------------- 🚀 About the Channel – Bharat Tech Show Here you will learn: ✔ Java Programming ✔ Data Structures & Algorithms ✔ Interview Preparation ✔ Coding Practice with clear explanation If you are preparing for placements or improving your coding skills, this channel is for you. 👉 Like | Share | Subscribe 👉 Turn on the Bell Icon 🔔 #Java #DSA #MatrixRotation #2DArray #CodingInterview #BharatTechShow
