feat: Multiply two 3x3 matrices using nested loops and store result in third matrix

🧠 Logic:
- Matrix A is multiplied with Matrix B (identity matrix) using the standard matrix multiplication algorithm.
- Uses three nested loops:
  - Outer two loops iterate over each cell in result matrix C.
  - Inner loop computes the dot product of row from A and column from B.
- Prints matrix C using enhanced for-each loop.

📌 Result is same as Matrix A because Matrix B is an identity matrix.
