Hello , Here is a code that is supposed to generate union of two array. The error with this code is that, the generated array contains redundent info which is not desired . Kindly identify the error and suggest solution.. Thanks in advance.. 
my @arr_in_1 =("User1","user2","user3");
my @arr_in_2 =("user2","user3","User4");

my @union_arr;

foreach my $arr_1(@arr_in_1)
{push(@union_arr,$arr_1);}
foreach my $arr_1(@arr_in_1)
{
     #print "The value in array 1 is :" .lc $arr_1."\n";
    foreach my $arr_2(@arr_in_2)
    {    
        #print "the value in array 2 is :". lc $arr_2."     \n";
        if (lc $arr_2 ne lc $arr_1)
        {
            push(@union_arr,$arr_2);
        }
    }
}
