Count Good, Sum Bad
In a list of numbers, you may want to measure positive and negative values separately. Write count_positives_sum_negatives, which returns a two-element list: the count of positive numbers and the sum of negative numbers. Zero is neither positive nor negative, and if the input list is empty, return an empty list.
