Array::Utils - small utils for array manipulation

SYNOPSIS

        use Array::Utils qw(:all);


        my @a = qw( a b c d );
        my @b = qw( c d e f );
        # symmetric difference
        my @diff = array_diff(@a, @b);
        # intersection
        my @isect = intersect(@a, @b);


        # unique union
        my @unique = unique(@a, @b);

        # check if arrays contain same members

        if ( !array_diff(@a, @b) ) {
                # do something
        }

=head1 DESCRIPTION

A small pure-perl module containing list manipulation routines. The module emerged because I was tired to include same utility routines in numerous projects.

FUNCTIONS

unique
Returns an array of unique items in the arguments list.

intersect
Returns an intersection of two arrays passed as arguments.

array_diff
Return symmetric difference of two arrays passed as arguments.
