A couple of quibbles to start:
- Please surround your code samples with <code>..>/code< tokens; this makes it easier to read
- Please do not use $a and $b as variable names; these are special
When I run you first case through the debugger, I get 'empty array' as the result of
$x = (qq/$a/ =~ qq/$b/)
I suspect that this is a more appropriate way of writing your use of the regex:
($n = $a) =~ /$b/;
With the proviso (I'm repeating myself) that $a and $b should not be used as variable names except in sort { $a <=> $b} @array;
