Well, consider it cheating, most spirals have a column width of 3 - so you may have to post it twice to have it accepted. cheers Simon

Using vile, for example, I do :set-unix-mode and save before uploading. If you're not doing this, then you are really hurting your score. By the way, in the ASCII Art contest I got the size down to 76. I would pay to see how "flagitious" did it in 71 bytes! > > >> puts f[w=gets(' ').to_i,gets.to_i].map{|i|['%3i']*w*' '%i} > >> ---------------------------------------------------------------- > >> > >> It draws a number spiral, starting with '1' in the upper left > >> corner and the highest number in the middle, it also features > >> spirals that are not quadratic. > >> > >> Yes, you will get some score at the codegolf site if you repost > >> this solution there > > > > If the site accepted this, then it wasn't tested thoroughly > > enough.

The site really should do more thorough testing. |
