unique values
Let's keep it easy this week as we get back into it.
Write a function called uniques
that takes a sequence of values. That sequence is going to have zero or more unique values. The rest will repeat at least once. Your job is to return the unique values in the same order as they appear in the argument sequence.
Examples
(uniques [1 2 3 4 5 6 1 2 3 5 6]) ;=> (4)
