Why are you using strict in golf if it is not required?

sub g {$n=pop;$h{abs($_-$n)}=$_ for@_;@s=sort{$a<=>$b}keys%h;$h{shift@
+s};}

66 chars with strict off

Update

sub g {$n=pop;$h{abs($_-$n)}=$_ for@_;@s=sort{$a<=>$b}keys%h;$h{shift@
+s}}

oops trailing ; is extraneous... 65 strokes...

Update2 oooh!

sub g {$n=pop;$h{abs($_-$n)}=$_ for@_;$h{(sort{$a<=>$b}keys%h)[0]}}

59 strokes

sort{$a<=>$b}keys%h

is too much, since $a<=>$b is the default sort. that leaves you with

sub g {$n=pop;$h{abs($_-$n)}=$_ for@_;$h{(sort keys%h)[0]}}

for 52.

did you test this? i think you'll find that $a cmp $b is the default.

Test your code...

that does not work... I tried it already... returns 20

How strange. I was using a different data set when I tested this, and it returned the correct answer.

Mea culpa.
