Sean A. Irvine: @Gennady, Please refrain from adding such trivial programs to sequences already having perfectly good programs.  Your submissions are costing a lot of editorial time and are of low value.  If you persist in such submissions, it is likely your access to the OEIS will be restricted.

Gennady Eremin: I don't take up editors' time. They ask me, and I answer.

03:51

Gennady Eremin: Yes, my programs are trivial. But all the programs are checked, and they work correctly.

03:51

Gennady Eremin: About indexes. Of course, in the Def function for each term, you can iterate over all ranges using conditional operators. But it is easier to process each range separately if the ranges do not overlap.

03:53

Gennady Eremin: The fact is that the number of ranges is always significantly less than the number of terms.
