LeetCode 189: Rotate Array | C++ | Brute Force to Optimal 3 Reversals

LeetCode 189 – Rotate Array explained in simple Hinglish with C++. We’ll first understand the Brute Force approach, why it takes O(N × K), and then optimize it using the 3 Reversals technique to achieve O(N) time and O(1) extra space. Complete explanation, code, pattern, and dry run step by step. #LeetCode #LeetCode189 #RotateArray #DSA #CPlusPlus #CodingInterview 📚 This channel is for beginners who want to master: • LeetCode • Data Structures & Algorithms (DSA) • C++ • Coding Interviews 👍 If you enjoyed the video, don't forget to Like, Share, and Subscribe! #leetcode #dsa #cpp #coding #algorithms
