Mobilized Monks,

Yes, it's "Yet Another Array Comparison Question". But for a particular case:

I have arrays of simple integers. All I want to do is test if @array_1 contains exactly the same set of integers as @array_2. Yes, or no.

So I figure I should be able to do:

@array_1 = sort(@array_1);
@array_2 = sort(@array_2);

And if they contain the same set of integers, I now have two identical arrays, even if the sort is ascii-betical instead of true numerical.

THEN - and here's my question - if I can convert the array into a string with no separators, I've got two strings to compare for equality. BUT - other than something heavy like

$string = join("", @array_1);
[download]

is there some other way to make my string?

Thanks

P.S. - other brilliant ideas are more than welcome!
