LeetCode 75 C++ | Step-by-Step Solutions (LAN Academy) - Sliding Window Algorithm – Problema pe care o primesc mulți la interviuri (LeetCode 1004 | C++)

Sliding Window is one of the most important patterns used in coding interviews. In this video we solve LeetCode 1004 – Max Consecutive Ones III using a clean and intuitive Sliding Window approach in C++. Instead of memorizing solutions, you'll understand the logic behind the pattern so you can apply it to many other problems. What you'll learn in this video ✔️ The intuition behind the Sliding Window technique ✔️ How to maintain a dynamic window with two pointers ✔️ When to expand and when to shrink the window ✔️ How to keep the number of zeros ≤ k ✔️ A clean C++ implementation in O(n) time This problem is a classic interview pattern and appears frequently in coding interviews. Problem LeetCode 1004 — Max Consecutive Ones III Flip at most k zeros to obtain the longest possible sequence of 1s. We solve it using a grow–shrink sliding window technique.
