feat: Reverse copy an array by iterating from end of source to beginning

🧠 Logic:
- Given array `A` is copied into array `B` in reverse order.
- Loop runs from end of `A` (`A.length-1`) to start, while inserting into `B` from index 0 onward.
- Demonstrates how to reverse an array during the copy process.
- Final result is printed using an enhanced for-loop.
