input: Write a function to construct and print an empty jagged array of a given size. The function should initialize the jagged array and populate each element with an empty list. If the given size is less than or equal to 0, the function should handle this case appropriately.

      if array_size <= 0:
          print([])
          return
      array = [None] * array_size

          array[i] = []
      print(array)

      print_jagged_array(array_size)
  assert print_jagged_array(4)==[[], [], [], []]
  assert print_jagged_array(0)==[]
  assert print_jagged_array(-1)==[]
