Traversing multiple lists at a time in perl

In general, when we iterate through multiple related lists at the same time, we often traverse with array subscripts:

My @ a = (...); my @ b = (...); my @ c; foreach my $I (0.. $# a) {my ($a, $b) = ($a [$I], $b [$I]); push @ c, $a + $b;}

In fact, it can also be like this:

Use List::MoreUtils qw (pairwise); my @ c = pairwise {$a + $b} @ a, @ b

Pairwise is only suitable for two lists, and three lists do this:

Use List::MoreUtils qw (each_array); my $ea = each_array (@ a, @ b, @ c); my @ d; while (my ($a, $b, $c) = $ea- > () {push @ d, $axium baccalaureate;} Thank you for reading!
