feat: Add two 3x3 matrices and print the result using enhanced for-loops

🧠 Logic:
- Define two 3x3 matrices A and B.
- Create matrix C to store the result of A + B.
- Use nested `for` loops to perform element-wise addition.
- Use enhanced `for-each` loops to print the resulting matrix C row by row.

 Explanation:
-Outer Loop:
 
-        for (int x[] : C) loops through each row (x[]) in the 2D array C.
+Outer Loop:
+for (int x[] : C) loops through each row (x[]) in the 2D array C.
 Here, x represents a 1D array (a row in the matrix).
-Inner Loop:
 
-        for (int y : x) loops through each element (y) in the current row (x[]).
+Inner Loop:
+for (int y : x) loops through each element (y) in the current row (x[]).
 y represents the individual elements of the row.
+
 Printing:
 
-        System.out.print(y + " ") prints each element (y) in the current row on the same line.
-        System.out.println(""); moves to a new line after finishing one row, ensuring the next row starts on a new line.
+System.out.print(y + " ") prints each element (y) in the current row on the same line.
+System.out.println(""); moves to a new line after finishing one row, ensuring the next row starts on a new line.
