Write a method stutter that takes an arraylist of strings and an integer k as parameters and that replaces every string with k copies of that string. for example, if the list stores the values ["how", "are", "you? "] before the method is called and k is 4, it should store the values ["how", "how", "how", "how", "are", "are", "are", "are", "you? ", "you? ", "you? ", "you? "] after the method finishes executing. if k is 0 or negative, the list should be empty after the call.
