It’s quiet hard to describe this problem but it’s easy to see it graphically:
x y
1 1
2 1
3 1
* 4 1 *
5 2
* 6 2 *
7 3
8 3
9 3
* 10 3 *
I have sorted a table by x, then sub-sorted by y. I need to return the x value of the last item in the sub-sorted table (the stared rows).
I’m aware of the LAST command, but I don’t know how to apply this recursively i.e. to each sub-sorted section.
Best,
Dan
