Implementation of sets using sorted lists

... set operations using sorted lists as the underlying data structure. Advantages: - Space savings -- lists ... - Fast operations depending on the underlying data patterns. - Non-overlapping sets get united, intersected, or differenced with only log(N) element comparisons.Results are built using fast-slicing. - Algorithms are designed ...
