hello monks :)

it's waaay too long i haven't been coding (at all), and especially coding in perl, so please forgive me for this dumb dumb dumb question. I haven't found it answered, so either I can't even properly search or it's so dumb nobody ever dared to ask.

my need : I've got two arrays, say : 
my @source=(1, 2, 3, 4, 5, 7);
my @target=(0, 1, 3, 4, 6);

[download]
and what I want is : 
@values_in_target_not_in_source would be (6, 0)
@values_in_source_not_in_target would be (2, 5, 7)

[download]

of course I can see plenty of solutions requiring to go throught the lists multiple times

I wish there was some kind of "elegant and yet efficient" (ok : perlish) solution

any idea ?

this is quite close but then I'd need to go throught one of the lists one more time :-/

In reply to compare arrays, and list the difference by iza
