by earl, 5307 days agoAnother day, another very nice Russ Cox post. At this rate, I'd suggest you continue to read Cox's stuff even without me pointing you towards it. This time I recommend Russ' fine summary of Briggs and Torczon's 1993 work on "An Efficient Representation of Sparse Sets" giving us constant-time insertion, membership testing and clearing of sets (with the usual time/space trade-off).
