Duplicated elements!
You have an array with duplicates, but you want only unique elements.
What can you do?
Use the Array#uniq method.
It’s a method that takes your array, and by converting it to a hash, and then back to an array again, it removes all the duplicates.
Pretty cool, right?
But there is more, the “uniq” method also takes a block.
Which allows you to do more advanced things.
