Compose a recursive program rruler.py similar in output to ruler.py but this time taking a command-line int argument and storing the output in a three-dimensional data structure as follows: $python rruler.py 1 $ [[[1]]] $python rruler.py 2 $[[[0, 0, 0], [0, 1, 0], [0, 0, 0]], [[0, 1, 0], [1, 2, 1], [0, 1, 0]], [[0, 0, 0], [0, 1, 0], [0, 0, 0]]] ...and so on
