Unique elements
There's a function in Clojure called distinct that removes duplicates from a sequence. Your task is to write a function called uniques that removes elements that appear twice.
Examples
(uniques []) ;=> ()
(uniques [1 2 3]) ;=> (1 2 3)
(uniques [1 1 2 3]) ;=> (2 3)
(uniques [1 2 3 1 2 3]) ;=> ()
(uniques [1 2 3 2]) ;=> (1 3)Thanks to this site for the challenge idea where it is considered Medium in Python. The problem has been modified from the original.

@farhadbuddy Note the use of “comp”. The set #{1} gets applied not to freqs but rather to the result of applying freqs to an element of xs.
