While browsing Vector to see if maybe my copy got
lost in the mail, I came across the following excerpt
regarding Sudoku on the main page.
http://www.vector.org.uk/
Not knowing K, I am not equipped to compare this
code with Roger's. Can anyone else?
****excerpt follows****
A K program: p is a 3 by 81 array of integers indicating the
'exclusivity group' for each board position; function s
solves Sudoku puzzles
p,:3/:_(p:9\:!81)%3
s:{*(,x)(,/[EMAIL PROTECTED];y;:;]'&21=x[&|/p[;y]=p]?!10}')/&~x}
****excerpt above****
Btw, I was unable to find a fresh Issue of Vector
since 22:4 in December 2004, unfortunately.
