Sliding window maximum | Deque based optimal solution | DSA interview problem

In this video, we solve the sliding window maximum problem using an efficient deque based approach.
This is a classic dsa interview question asked in FAANG, product-based companies, and coding rounds.
We explain why brute force is inefficient, how the deque maintains useful elements, and how to get the maximum for every window in O(n) time.
