I didn't really get the ALGOL one. My first Delphi version
was using bitmaps and marking endangered fields, but the
code was pretty horrible because i found no elegant way
to fill the diagonals but using 2 loops (~ 20 lines of
not very intuitive additional code)
I find the current version to be quite nicely readable,
while the bitmap solution would probably be faster.

Depends. The solution often reflects how certain problems
are handled in a language.

I have some tests that require to solve an problem, and some
that require to use an certain algorith. I think you can
encounter both situations in real life. Of course, saying
"A needs 20 lines so its better than B which needs 22 lines"

Thanks, i allready had lots of submissions by mail this

Good questions. Any ideas for solutions?
He screamed: THIS IS SIG!
