💡 What you’ll learn in this video:
- What is the Dynamic Sliding Window technique
- How to handle at most k invalid elements
- How to expand and shrink a window efficiently
- How to track maximum subarray length
- Step-by-step beginner-friendly explanation
⚡ Approach Covered:
🔹 Sliding Window (Optimal Approach)
