Fruits Into Baskets | From Brute Force to Optimized Sliding Window | C++, Java, Python

In this video, we solve the Fruits Into Baskets problem step by step — starting from the brute force approach and then moving to the optimized Sliding Window solution. This question is a classic example of “longest subarray with at most 2 distinct elements.” Instead of directly jumping to the optimal solution, I first show how brute force works, why it is inefficient, and then how to think in terms of expanding and shrinking a window to reach an O(n) solution. If you are preparing for placements or interviews, this pattern is extremely important. Many problems are built on the “at most K distinct elements” idea, and once you understand this properly, multiple questions become easy. In this video, you will learn: Brute force approach and its time complexity Transition from brute force to optimized thinking Sliding window with HashMap Clean implementation in C++, Java, and Python This is part of my pattern-wise DSA series on Sliding Window. Master the logic, not just the code.
