:point_right: You might want to use a for loop here instead of while.

A for loop would make it easy to create an index which you could then use to subscript your arrays while comparing the values. Remember that you're looking for a match with the previous value of the same array.

Also, while it won't affect passing the challenge, you were probably expected to add the code for the new class to the RepeatDetector.cs file.
