I need to compare two arrays to make sure they do not share any of the same elements. For instance, if the two arrays are

@mammals = (dog, cat, mouse, horse, planet);

@sky = (star, planet, galaxy, nova, comet);

I want a program that would tell me, "planet is in both arrays." Or if no elements are shared, it would print "Both arrays are unique."

The actual arrays I have contain just numbers. Thousands of numbers, so it is too much to check them visually.

I have no clue how to do this.

Update

Should have written:

use strict;
use warnings;
@mammals = qw(dog cat mouse horse planet);
@sky = qw(star planet galaxy nova comet);

Sorry. This is my first post.
