* (Game: lottery) Revise Programming Exercise 3.15 to add an additional $2,000   *
* award if two digits from the user input are in the lottery number. (Hint: Sort *
* the three digits in the lottery number and three digits in the user input into *
* two lists, and use the Collection’s containsAll method to check whether the    *
* two digits in the user input are in the lottery number                         *
