Hello
I am trying to output the duplicate elements in an array. I looked into
the api of ruby I found uniq method which outputs the array with no
duplication. What i want is to know which elements is duplicated.
For example
array = ["apple", "banana", "apple", "orange"]
=> ["apple", "banana", "apple", "orange"]
array.uniq
=> ["apple", "banana", "orange"]
I want the method to tell me that apple is the duplicated element
I tried this but it does not work
array - array.uniq
any idea
Regards
