Hi, I'm new to J. I like what I see so far.
Here is simplified version of the problem I'm trying to solve. N =: i.10 M =: |. i.10 < \ (|. N) * M │81│81 64│81 64 49│81 64 49 36│...│81 64 49 36 25 16 9 4 1 0│ But what I want is actually the reverse of the cumulative window. Not the reverse of the entire list N -- only the reverse of N after N is broken into a segment. The result I'm trying to get: |9 * 9|9 * 8 8 * 9|9 * 7 8 * 8 7 * 9|9 * 6 8 * 7 7 * 8 6 * 9|... etc Which is |81|72 72|63 64 63|54 56 56 54|... etc Thanks, -Steven P.S.
