Fair enough -- I guess I focussed more on the description rather than the code of the OP:
Is there a way to select multiple values from the array without repetition?
I interpreted the description as meaning "unique" elements of the array, which my solution will provide. So, there seems to be a discrepancy between the OP description and code.
