Re: Comparing arrays in perl.

Hi anand_perl,

Here is one way to do it. Also you can use some array modules to accomplish the same.

use strict;
use warnings;

my @arr1 = ("one","two","three","four","five");

my @arr2 = ("one","a","b","one","c","d","e","two","f","g","h","two","i
+","j","two");

my @arr3; my %hash;

for my $arr2 (@arr2){
    
    if (grep $arr2, @arr1){
        
        $hash{$arr2}++;
        
    }else{
        
        push (@arr3, $arr2);
        
    }
    
}

push (@arr3, keys %hash);

print "@arr3";

output:
-------
e a d two j c h one g b f i
