You are given a list of integers containing duplicate elements. The task is to generate a second list, which contains only the duplicate elements. In simple words, the new list should contain elements that appear more than once. Write code that takes input from a user, creates a list and then prints the cleaned- up list as output. Example: Input list = [10, 20, 30, 20, 20, 30, 40, 50, -20, 60, 60, -20, -20] Output: output_list = [20, 30, -20, 60]
