Sliding Window
The sliding window is an optimization technique used to solve problems involving arrays or strings by maintaining a subset (window) of elements and moving it across the data. It reduces unnecessary recalculations, making it efficient for tasks like subarray sums, maximum/minimum ranges and pattern matching, often achieving O(n) time complexity.
