​@CodeXPrasoon Rotate Array in Java | Reverse Algorithm Explained with Dry Run | Java Coding Interview Question rotate array in java array rotation in java java reverse algorithm reverse method in java java array interview questions java array rotation dry run rotate array by k steps java array right rotation java reverse an array in java rotate array using 3 reversal method java coding interview questions java array problems dsa array rotation java rotate array coding interview array program in java 🚀 In this video, we will learn how to Rotate an Array in Java using the most popular and optimized approach – 3 Reversal Method. This is one of the most asked coding interview questions in companies like TCS, Infosys, Wipro, Accenture, Cognizant, and product-based companies as well. 🔑 Key Points Covered in this Video: 1️⃣ What is Array Rotation in Java? 2️⃣ How to rotate an array to the right by k steps? 3️⃣ Handling cases where k array length (using modulo operator). 4️⃣ Step-by-step dry run of the 3 reversal method: Reverse whole array Reverse first k elements Reverse remaining elements 5️⃣ Printing the final rotated array. 📝 Example: Input Array: {10,20,30,40,50,60,70} Rotate by k = 3 steps → Output Array: {50,60,70,10,20,30,40} 📚 Code Explanation: ✔️ Reverse Method → swaps array elements between start and end. ✔️ Main Logic → uses three reversals to achieve rotation in O(n) time & O(1) space. ✔️ Efficient & Interview Friendly → No extra space required, easy to explain. ✅ Don’t forget to Like 👍, Share 🔄, and Subscribe 🔔 for more Java interview coding questions, data structures, and algorithms explained in Hindi + English for beginners to advanced. #Java #ArrayRotation #CodingInterview #DSA #JavaProgramming #RotateArray #javaforbeginners #Java #ArrayRotation #RotateArray #DSA #CodingInterview #JavaProgramming #LearnJava #JavaForBeginners #JavaTutorial #Programming #ReverseAlgorithm #InterviewPreparation #JavaDeveloper #CodingProblems #DataStructures
