feat: Display 2D array elements using nested for-each loops

🧠 Logic:
- Define a 2D array (`matrix`) with 3 rows and 3 columns.
- Use an outer for-each loop to iterate over each row (1D array).
- Use an inner for-each loop to iterate over each element of the row.
- Print elements in a structured matrix format, row by row.

 Immutable Collections: When you don't intend to modify the collection/array.

 Key Points to Remember:
 Read-Only Access:
-You can use the for-each loop to read the elements but cannot modify the array or collection elements directly. Modifications should be done with a standard for loop using indices.
 
-Works with Arrays and Collections:

+Modifications should be done with a standard for loop using indices.
 
+Works with Arrays and Collections:
 For-each loops are compatible with arrays and classes that implement the Iterable interface (e.g., ArrayList, HashSet).
 
 No Manual Indexing:
 If you need indices, you'll need to use a traditional for loop instead.
 
-The for-each loop is ideal for reading elements of arrays or collections. However, if you need indexing or want to modify elements, you should use a traditional for loop.
-It's a matter of choosing the right tool for the task. 😊
