public static void main(String[] args) {
int [] arr = new int [] {1, 2, 3, 4, 5};
System.out.println("Original array: ");
for (int i = 0; i < arr.length; i++) {
System.out.print(arr[i] + " ");
}
System.out.println();
System.out.println("Array in reverse order: ");
for (int i = arr.length-1; i >= 0; i--) {
System.out.print(arr[i] + " ");
}
}
