Learn fixed-size sliding window for subarray calculations like maximum average, moving average, and k-size subarray problems.
Master monotonic queue (deque) to find maximum or minimum in sliding windows efficiently in O(n) time.
Master variable-size sliding window for condition-based problems like longest substring without repeating characters.
Learn sliding window with character frequency matching for anagram and permutation substring problems.
