Learn how the sliding window technique efficiently computes the maximum sum of a subarray of fixed length, reducing time complexity from O(nĀ²) to O(n) with constant space.
Explore multiple approaches to count unique values in sorted arrays, from hash-based solutions to optimal in-place pointer techniques with O(n) time and O(1) space complexity.
Learn how to efficiently compare arrays and strings using the frequency counter pattern, avoiding O(nĀ²) complexity.
