Is there a more efficient way to convert a Set to a descending list? I was looking for a function similar to Set.toAscList something like Set.toDecList . I feel first converting to a ascending list and then reversing may be in-efficient given that I actually don't need all the elements only a last couple of elements..
Why don't you use something like take N $ Set.toAscList s then? "A last couple of elements" in descending list would be "a first couple of elements" in ascending list. That approach may even be *faster* than building descending list, because to get your elements you'll build only beginning of the list, while with descending list, you'll need to build whole list in order to get last elements. -- Regards, Alexander Batischev 1024D/69093C81 F870 A381 B5F5 D2A1 1B35 4D63 A1A7 1C77 6909 3C81
