Set::Intersection - provides an API to get intersection (of set theory) of ARRAYs.
use Set::Intersection; my @arr1 = qw/3 1 4 1 5 9/; my @arr2 = qw/1 7 3 2 0 5/; my @intersection = get_intersection(\@arr1, \@arr2); # got (1, 3, 5) in @intersection
Returns intersection set (as LIST) of all ARRAYs.
- The result LIST is uniqized and unordered.
- If no ARRAYs passed, the result LIST is empty.
- If only one ARRAY passed, the result LIST is same as the passed. (elements won't be uniqized nor order-changed)
- If you have undef in any LIST, you'll be warned.
