Oh no, more code golf!

A new code golfing site. Gaaaak!

If I have time to work on such diversions, I’ll post mine under the ID numbercruncher.


Played with the starburst code. Have something that works (though they failed to specify their input method, or their output requirement, e.g. newlines, etc.) This is at 135 characters:

$l=@a=split//,shift;$i=-1;while($i++< $l){map$x[$_]=" ",0..$l;$i==int$l/2?@x=@a:map$x[$_]=$a[$i],$i,$l/2,$l-$i-1;print join"",@x,"\n";}

which for the input “asdfd” gives

a a a 
d d d 

among other things. Works well for the other input. In the debugger. Their code testing environment, not so much. So I have to reverse engineer this.

Apart from that, I see areas where I can save quite a few characters, 30-50, if I could avoid some initialization, and some of the formatting bits.

[update 2]

started exploiting some of the more powerful features of Perl, though I kept generating more temporary variables.

($l=@a=split//,<>)--;$\=pop@a;$m=$l>>1;map{@x=(" ")x$l;$_==$m?@x=@a:(@x[$_,$m,$l-$_-1]=($a[$_])x3);print@x;}0..$l;

115 characters. If I could eliminate some of the temp variables (carefully), could probably get it below 100 characters. Its still … almost … readable by humans. There are 3 vector assignments, a vector printing, and a serialized outer loop. The map{} is the core, the $l=.. gets the input and divides it up into an array.
