Write a method List-Double> duplicates(List<Double> input) that returns a List of all duplicates in the input List. You may assume occurs either once or twice. The expected runtime must be O(n) where n is elements (no credit for slower runtimes, so you cannot sort the input).(0 Examples: input = [3,4,4] input [3, 7,4, 7,3] return [7, 3] that each element the number of points) return [4] List Double duplicates(List<Double input)(
