Title
Body
I'm currently enumerating through NSMutableArray (or NSMutableSet ) elements to find duplicates and remove them. For example, if array/set has values [@"a", @"b", @"b", @"c"] , the end result should be [@"a", @"b", @"c"] . Since I'm comparing NSStrings , I'm using isEqualTo: method to check if strings are equal. Is there a more efficient way to do remove duplicate entries than to loop through all of them and check if duplicate exists?
