Interviewers instantly flag nested loops when a single pass will do. Alvin reveals how the sliding window technique transforms clunky exponential code into elegant linear solutions. He dissects the exact mechanics of fixed and variable windows to conquer advanced array problems.
Key insight: Even with a while loop nested inside a for loop, a variable sliding window algorithm strictly runs in O(N) time—not O(N^2)—because the start and end pointers never reset backwards.
