LC 1888 - Minimum Flips to Make Binary String Alternating | Sliding Window O(n) | LeetCode Explained

#leetcode #slidingwindows #algorithm #dsa #faangpreparation In this video, we solve the LeetCode problem: “Leetcode 1888 : Minimum Number of Flips to Make the Binary String Alternating” We use a Sliding Window approach to achieve: ✅ O(n) Time Complexity ✅ O(1) Space Complexity This problem looks simple at first, but the key insight is handling rotations efficiently and comparing against both possible alternating patterns. 🧠 What You’ll Learn: How to think in terms of two alternating patterns: 010101... and 101010... Why doubling the string helps in rotation problems How sliding window helps avoid recomputation How to track mismatches efficiently How to optimize to constant space 💡 Key Concepts Covered: Sliding Window Technique String Rotation Handling Greedy Pattern Matching Optimized One-Pass Solution ⏱ Complexity: Time: O(n) Space: O(1) If you're preparing for coding interviews or solving daily LeetCode problems, this video will help you strengthen your pattern recognition + sliding window skills.
