Hi all! I would like to know if it's possible to make an array sorting with
a subroutine call.
Usually, a sort is made as, for example:
sort {$a <=> $b} @array;
But my intention is something like:
sort subroutine_call @array;
sub subroutine
{
$a <=> $b;
}
How could I do it?
Hello Sergio
It will work almost exactly as you have written it. Just use the name of
the subroutine in the call to sort:
sort subroutine @array;
sub subroutine {
$a <=> $b;
}
HTH,
