Wow, that's compact :) Can I post it to the wiki?
A few process questions for everyone: 1. If you post your solution here and would like to have it on the wiki, I or someone else can do it. Please just indicate that it can be posted. You can just have a blanket statement like "this and future solutions can be posted to the wiki" 2. What do you think of measuring the clock time for coming up with the solution? I think it would be a useful data point for others to learn how quickly solutions can be solved in J. I'll go back and update the wiki with my times (rough times since I didn't time it).
