Set::Intersection - provides an API to get intersection (of set theory) of ARRAYs.
Version 0.04;
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
get_intersection
get_intersection()
get_intersection([\%options,] [\@ARRAY[, \@ARRAY[, ...]]]);
Returns intersection set (as LIST) of all ARRAYs.
The result LIST is uniqued and unordered.
If no ARRAYs are passed, the result LIST is empty.
If only one ARRAY is passed, the result LIST is same as that passed. (In this case, elements won't be uniqued nor will the order bechanged.)
If you have undef in any LIST, you'll be warned.
undef
%options
-preordered => BOOLEAN
To reduce calculation time, get_intersection() sorts ARRAYs by their length before calculating intersections.
This option tells that order of ARRAYs are well done, and calculation of intersection will be based on left most ARRAY.
