That work with Racket is coming in handy!

I'm a big python fan, but am really starting to like racket. I just wish more people would give it a go! I'm watching the s.i.c.p videos, and just had to check it out!

One thing that helps me alot, is make a list of the first 5 or more solutions. Then make a list of deltas for that list, another list of deltas for the delta list, and so on till I get a list that doesn't change. This really helps me see the patterns.

very cool. I wish katas like this would have a rank of say 7 to get functionality, then maybe 6 for the aha moment whey you recognise the patterns, and do it without a nested loop.
because the first job would be easy, you can start generating numbers . Then you see the first pattern... Then after a bit more work, the second one.
Overall, I like these kind of pattern recognition ones.

very cool, looking foward to 3d version.

This seemed SO easy,
many attemps later...
finally.

I liked this kata a lot.

I don't understand the low score at all, this is a perfect example of what I want to do with a program. Solve problems. Physics problems especially. Great Kata.

This is very cool!
Thank you.

I liked this, similar to walking thru it without wizadry, but still elegant.

i'll second that!

That's cool. Thanks for the tip. I NOW remember seeing this ages ago, but I really liked this puzzle.
Of course, I just programmed it like I was going to plot it, nothing this cool.

Yea, I agree.

I know, it's just from the description.
