    //Let's practice calling different methods by writing our very own methods. You will write and save methods in the space below
    //that call the existing methods you see already written here.  Ready?  Let's Go!
    
    
    //Sample: Here is a public method that calls the getCitiesForExpansion below and prints the results to our debug log
    public static void printOutCitiesForExpansionDemo() {
        //The code on the left of the equals sign instantiates a list of Strings, the code on the right side calls our method and returns a list of cities

        System.debug('Here are the cities: ' + cities);
    }
    
    
    //1.  Write a public method that calls the getCitiesForExpansion method to get a list of cities, then add
    //another city to the list before printing it to the debug log.
    //(see the sample above for an example of calling that method-You can even start by copying and pasting that method here, renaming and modifying it)
    public static List<String> addAndPrintoutCitiesDemo(){

        return cities;
    } 
    
    //2.Write a public method that calls the isTopSalesCity method and prints out the returned boolean to the debug log.
    //You'll need to pass in a string variable that is a city name as the argument!
    public static void isTopSalesCityDemo(){
        for(String city : addAndPrintoutCitiesDemo()){
            System.debug('Is '+city+' a top city? :'+isTopSalesCity(city));
        }
        
    }
    
    
    //3.  BONUS!!  If you've finished the first two, there's another public method below that will return the top 10 Accounts
    //Write a public method that calls getTopTenAccounts.  Can you loop through those accounts and change the name of those accounts with a DML Update?
    public static void accountsTopTenDemo(){

    //This method will give you the top ten account records, based on Annual Revenue
    //You don't need to know exactly how the method you're calling works, we'll cover SOQL queries later, but take a look and you'll likely get the gist
    //What's important to know is that when called it will return a list of top Accounts based on revenue, returning no more than 10.
    public static List<Account> getTopTenAccounts() {
        
        List<Account> topAccounts =

Hi Asmita, good work this week. Here are some notes:
Exercise 1: you went beyond what was asked, by returning a List. Since you declared that in line 19... WELL DONE! (You also added more cities than required, but you did that with correct syntax.)

Exercise 2: NOW I see why you wanted to return something in Exercise 1, and I love that you used it here! Nice use of the isTopSalesCity(city) within the System.debug(), and putting the System.debug() within the loop. I can tell from your code that you're enjoying this! One note -- I'd recommend putting some spaces around the + when you're concatenating strings. Easier to read.

Exercise 3: perfect.
