I like this example. What would you do if the values in array1 were not unique?

Perhaps something like the following:

```use strict;
use warnings;
use List::Util 'min';

my %array1Hash;
my @array1 = ( 5,   2,   1,   4,   1,   6,   7 );
my @array2 = ( "a", "b", "c", "d", "e", "f", "g" );

push @{ \$array1Hash{ \$array1[\$_] } }, \$_ for 0 .. \$#array1;
my %array2Hash = map { \$_ => \$array2[\$_] } 0 .. \$#array2;

my \$array1Min = min @array1;
my \$positions = join ', ', @{ \$array1Hash{\$array1Min} };
my \$elements  = join ', ', map \$array2Hash{\$_}, @{ \$array1Hash{\$array1
+Min} };

print 'The minimum value in @array1 is ', "\$array1Min.\n";

print 'The position(s) of ', \$array1Min, ' in @array1: ', "\$positions.
+\n";

print 'The element(s) in @array2 at position(s) ', "\$positions: \$eleme
+nts.";

Output:

```The minimum value in @array1 is 1.
The position(s) of 1 in @array1: 2, 4.
The element(s) in @array2 at position(s) 2, 4: c, e.
