This approach is merges the construction of the %seen hash with the extraction of unique elements. 1. reading elements from @array 2. If the current element ($_) and it is not in the hash (%seen), it will push into @result. Then it stored into hash(%seen). As we know hash will not allow duplicate value Thanks Gopal
