Hints/Clarifications:

• For the Factors.java file: the pre- and post- conditions above addNextFactor
  apply only to the method addNextFactor, not to any other method or constructor.
  • NEW: That means, you don’t need to worry about order in the constructor. Just take the elements in the order they come.
• If the notation for (int i: nums) is unfamiliar; it was covered in the chapter. Do your best to infer what it means, and answer on that basis.
• For number 7, the blank should simply be filled with an expression that correctly initializes the variable lastElement.
• remove in java.util.ArrayList “Removes the element at the specified position in this list. Shifts any subsequent elements to the left (subtracts one from their indices).” (But I don’t think you need this.)
