The Sliding Window pattern is one of the most vital algorithmic techniques for optimizing array and string problems. Instead of repeatedly processing overlapping subarrays - which leads to brute-force quadratic O(N^2) or O(N*K) complexities, the sliding window technique reuses previous computati...
