Hey, This thing..(my browser) keep me logging out..? Why?
Hi, Here is the code snippet:
Given @a and @b, you have to get @c
I am looking for better method and faster method;
Also, If anyone can think of more general formula, that would be helpful to combine multiple array.
The numbers in the arrays are just place holders
It could be @a = qw(1.2.3 4.5.6 1.2 1.7.9 2) etc..
In other words, simple sorting would not work
Thanks, Artist 
#!/usr/bin/perl
@a = (3,5,2,6);
@b = (7,3,6);
map { $x{$_} = -1 } @a;
map { $x{$_} += 1 } @b;
foreach (sort keys %x){
        $val = $x{$_};
        if(!$val) { print "$_:$_"; }
        elsif($val > 0){ print "-:$_"}
        else{ print "$_:-"};
        print "\n";
}
#@c = ( [2,'-'],[3,3],[5,'-'],[6,6],[7,'-']);
