Given a set, weights, and an integer desired weight, remove the element of the set that is closest to desired weight (the closest element can be less than, equal to OR GREATER THAN desired_weight), and associate it with the variable actual_weight. For example, if weights is (12, 19, 6, 14, 22, 7) and desired_weight is 18, then the resulting set would be (12, 6, 14, 22, 7) and actual_weight would be 19. If there is a tie, the element LESS THAN desired_weight is to be chosen. Thus if the set is (2, 4, 6, 8, 10) and desired_weight is 7, the value chosen would be 6, not 8. Assume there is at least one value in the set.
