Re: how to loop through many arrays

in reply to how to loop through many arrays

My only advice is to just do it. You can compile the arrays into a list of arrays, or you could add them to a hash where you give each a name. Either way, just iterate on each array and use List::Util->reduce to determine the position of the max element.

use List::Util qw(reduce);

use strict;
use warnings;

my @array1 = (1,2,3,4,8);
my @array2 = (1,4,2,4,5);
my @array3 = (1,6,1,7,5);

for my $array (\@array1, \@array2, \@array3) {
    my $max_pos = reduce {$array->[$b] > $array->[$a] ? $b : $a} keys 
+@$array;
    print "Max is $array->[$max_pos] at position $max_pos\n";
}

=prints
Max is 8 at position 4
Max is 5 at position 4
Max is 7 at position 3
