Duplicated Numbers 分数 10 作者翁恺单位浙江大学 This program reads a lot of integers, in which may be duplicated numbers. The program picks out all the duplicated ones and sorts the remainders in a descendent order. 函数接口定义： public static ArrayList<Integer> pick(ArrayList<Integer> a); a is the ArrayList to be parsed and returns the result as an ArrayList.
