 | It's pretty vague. Can you give examples of other kinds of "operators" and "iteration patterns"?  |
 | I don't believe that you ever really meant this: for(Observer user : users){ for(Product currentProduct : products){ currentProduct.addObserver(user); currentProduct.setAvailable(true); } } You meant this: for(Product currentProduct : products){ for(Observer user : users){ currentProduct.addObserver(user); } currentProduct.setAvailable(true); } The first way it adds the first user then notifies him for each product, … |

 | You could use the stack. Push the digits as you generate them. Then in a second loop, pop the digits and print them. You need to know when you've popped the last digit which you can either do with a counter or a sentinel value. Here's some pseudocode that uses …  |
