For python: Write A function lowest_unique_K(K, List) which takes a positive integer K and a list of real numbers List, and returns an ordered (ascending) list of the lowest K unique numbers in the list List. For instance, lowest_unique_K(3, [-0.5, 3, 3, 2, 6, 7, 7]) would return [-0.5, 2, 3]. The function should not modify the original list List.
