Скачать или смотреть Master the Sliding Window Pattern – The Secret to O(n) Array & String Algorithms!

Master one of the most powerful optimization techniques in computer science! In this high-fidelity visualization, we break down exactly how the Sliding Window pattern works, when to use it, and why it transforms brute-force O(n²) solutions into elegant O(n) algorithms.

What you’ll learn in this video:
✅ What the Sliding Window pattern really is (fixed vs variable window)
✅ When Sliding Window is better than brute force
✅ How pointers move and why no elements are reprocessed
✅ How to track window state (sum, count, frequency maps)
✅ Why O(n) is a game-changer for competitive coding & interviews

Whether you’re grinding FAANG interviews, solving LeetCode problems, or building algorithmic intuition, this visual guide will make the Sliding Window pattern click instantly.
