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.
