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.

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

Mea culpa.

Must be the decimals or something... I thought it would work, too
