in reply to Check if element in One Array Exist in Other Array

Take a look at List::Compare::Functional Module.

Update

use List::Compare::Functional qw(is_LsubsetR); $test1 = ['A','D','B']; $test2 = ['A','C','B']; $source = ['A','B','C','A','B']; $result = is_LsubsetR( [ $test1, $source ] ); $result == 1 ? print "\n\$test1 is True" : print "\n\$test1 is False"; $result = is_LsubsetR( [ $test2, $source ] ); $result == 1 ? print "\n\$test2 is True" : print "\n\$test2 is False";

OUTPUT

$test1 is False $test2 is True
