Max Consecutive Ones III | Brute Force to Optimal (O(n)) | Sliding Window Explained

In this video, we solve Max Consecutive Ones III (LeetCode 1004) step by step — starting from the brute force approach to the fully optimized sliding window solution. I’ve explained: O(n²) brute force solution Better 2n approach Optimal O(n) sliding window solution Why sliding window works here How to think about k zero flips Time and space complexity comparison If you struggle with sliding window problems, this video will help you build clear intuition instead of just memorizing the pattern. Perfect for: DSA preparation, coding interviews, product-based companies, and placements. Watch till the end to clearly understand how to reduce time complexity from quadratic to linear. Master the logic, not just the code.
