Consider the following list of variables:
11673326
11673329
11673325
11673330
11673321
11673335
I'm trying to write a function which finds the next larger number (larger than the argument).
Example: If the input if 11673326 the output is 11673329, if the input is 11673335 the variable should be undefined, if input is 11673321 the output should be 11673325.
What I have tried:
my $current = 11673326
my ($next,@status);
@status = <DATA>;
$next = $current;
foreach my $row (@status)
{
chomp($row);
if(looks_like_number($row) && $current < $row && ($next == $cu
+rrent || $next > $row)) {
$next = $row;
}
}
__DATA__
11673326
11673329
11673325
11673330
11673321
11673335
But it doesn't quite work. Where is the problem and how to solve it? Is there a better solution? I prefer not to use any other functions or modules. Can I do it some how with regex?
