Comparing arrays in perl
Hi all,

I am trying to compare two arrays in perl using the following code.
foreach $item (@arrayA){
push(@arrayC, $item) unless grep(/$item/, @arrayB);
}

The above code stores in arrayC all the elements of arrayA that do not belong in arrayB. The problem is the following.

If for example @arrayA[3]=1121 and @arrayB[13]=11213456
The above code will return that 1121 of arrayA exists in arrayB. This is not correct. How can i overcome this?

Best regards,
Christos

I will suggest using

List::Compare module from CPAN

List::Compare - Compare elements of two or more lists - search.cpan.org

this is very handy and useful
