This is a faq: How do I compute the difference of two arrays? How do I compute the intersection of two arrays?

If what you want is to see if a scalar is in the array, you can try grep: 

print +(grep {$_ eq $elem} @array) ? "Yes" : "No";

Or

my %h = map { $_ => 1 } @array;
print defined $h{$elem} ? "Yes" : "No";

Update: Changed the grep regexp by eq (see the comment below from davorg)
