Re^2: Need to Create an Array of Differences

I ended up doing something like this:

# given @a, @b
my %a;
@a{@a} = ();
delete @a{@b};
my @c = keys %a;

This code works just as well as my previous code with the exception that the new code is much faster. Thanks!

I assume the code does what you need, but there are a few caveats that should be mentioned. This code will change the order of the values, and it will eliminate any duplicates. This may or may not be a problem, depending on what it's being used for. Update: these caveats were noted, in Zaxo's original node, I just failed to notice. My apologies.	[reply]
