Perfect for coding interview prep, DSA practice, and LeetCode beginners. Watch till the end to learn the cleanest JavaScript solution with full explanation. 🚀 Topics Covered: Brute Force (Plain Loop Method) Extra Array Approach Optimal Reverse Technique (O(n) Time, O(1) Space) Step-by-Step Explanation with Example 🎓 Great for: DSA Practice, FAANG Interviews, JavaScript Coders, and LeetCode Learners. Approach: Use the array reversal technique to rotate elements in-place. Reverse the entire array — this moves the last k elements to the front but in reverse order. Reverse the first k elements — this restores the original order for the rotated front part. Reverse the remaining n−k elements — this restores the original order for the rest of the array. By combining these three reversals, the array effectively gets rotated to the right by k positions without using extra space. Complexity Time Complexity: O(n) - Each element is swapped at most once in three reversals. Space Complexity: O(1) - Rotation is done in-place using only a few temporary variables. #LeetCode #RotateArray #CodingShorts #DSA #JavaScript #CodingInterview #LeetCodeSolution #DataStructures #Algorithms #CodeWithMe #Programming #CodingChallenge #LearnToCode #LeetCode189 #ReverseArray #ArrayRotation #DSATutorial #CodeShorts #TechInterview #CodingExplanation leetcode, rotate array, leetcode 189, rotate array solution, rotate array javascript, rotate array python, rotate array explanation, leetcode shorts, dsa shorts, coding interview, coding tutorial, javascript dsa, array problems, array rotation in place, reverse array approach, data structures and algorithms, coding challenge, leetcode solution explained, rotate array brute force, rotate array optimal, leetcode array problems, interview prep, programming shorts, how to solve rotate array, code explanation, leetcode javascript, dev tutorials, dsa coding ,dsa in javascript, javascript coding interview questions
