 This module includes hands-on activities that guide you through the process of building and running demonstration code. You're encouraged to complete these activities using Visual Studio Code as your development environment. Using Visual Studio Code for these activities will help you to become more comfortable writing and running code in a developer environment that's used by professionals worldwide.

 ### Create an array of pallets, then sort them

-   > [!NOTE]   > Program.cs should be empty. If if isn't, select and delete all code lines.

 1. Type the following code into the Visual Studio Code Editor:
-   ```csharp   string[] pallets = { "B14", "A11", "B12", "A13" };
-   Console.WriteLine("Sorted...");   Array.Sort(pallets);   foreach (var pallet in pallets)   {       Console.WriteLine($"-- {pallet}");   }
-   ```
+
+    ```csharp
+    string[] pallets = { "B14", "A11", "B12", "A13" };
+
+    Console.WriteLine("Sorted...");
+    Array.Sort(pallets);
+    foreach (var pallet in pallets)
+    {
+        Console.WriteLine($"-- {pallet}");
+    }
+
+    ```
 
 1. Take a minute to review the `Array.Sort(pallets);` line from the previous code you added.
-   Here you're using the `Sort()` method of the `Array` class to sort the items in the array alphanumerically.

 ### Reverse the order of the pallets
 
 1. To reverse the order of the pallets using the `Array.Reverse()` method, update your code as follows:
-   ```csharp   string[] pallets = { "B14", "A11", "B12", "A13" };
-   Console.WriteLine("Sorted...");   Array.Sort(pallets);   foreach (var pallet in pallets)   {       Console.WriteLine($"-- {pallet}");   }
-   Console.WriteLine("");   Console.WriteLine("Reversed...");   Array.Reverse(pallets);   foreach (var pallet in pallets)   {       Console.WriteLine($"-- {pallet}");   }
-   ```
+
+    ```csharp
+    string[] pallets = { "B14", "A11", "B12", "A13" };
+
+    Console.WriteLine("Sorted...");
+    Array.Sort(pallets);
+    foreach (var pallet in pallets)
+    {
+        Console.WriteLine($"-- {pallet}");
+    }
+
+    Console.WriteLine("");
+    Console.WriteLine("Reversed...");
+    Array.Reverse(pallets);
+    foreach (var pallet in pallets)
+    {
+        Console.WriteLine($"-- {pallet}");
+    }
+
+    ```
 
 1. Focus on the line of code `Array.Reverse(pallets);` line from the previous code you added.
-   Here, you're using the `Reverse()` method of the `Array` class to reverse the order of items.

-   Reversed...   -- B14   -- B12   -- A13   -- A11
-   ```
+
+    ```Output
+    Sorted...
+    -- A11
+    -- A13
+    -- B12
+    -- B14
+
+    Reversed...
+    -- B14
+    -- B12
+    -- A13
+    -- A11
+
+    ```
 
 ## Recap
 
 Here's a few important ideas that you covered in this unit:
 
 - The Array class has methods that can manipulate the size and contents of an array.
 - Use the `Sort()` method to manipulate the order based on the given data type of the array.
-- Use the `Reverse()` method to flip the order of the elements in the array.
