(To be fair, that is not what I said, so I got it wrong too. Nonetheless, FSet won’t work for me. I need to keep track of individual overlapping intervals without merging them.)<div><br><div><div>On Oct 27, 2018, at 10:52 AM, Scott L.

FSet merges intervals that overlap or abut while from what I see on Wikipedia, these interval trees don't do that. It's the difference between a set represented as a collection of intervals, where we care only what numbers are in the set, versus a set of intervals that we want to remember as pairs. Depending on your requirements, either of these might fit your needs better.</div><div><br></div><div>-- Scott<br></div></div><br><div class="gmail_quote"><div dir="ltr">On Sat, Oct 27, 2018 at 10:33 AM Scott L.
