input: Write a function to construct and print a jagged array with a given size but without any values. The function should initialize an empty jagged array of the specified size and then print it.
  assert print_jagged_array(4)==[[], [], [], []]
  assert print_jagged_array(2)==[[], []]
  assert print_jagged_array(1)==[[]]
  assert print_jagged_array(0)==[]
  assert print_jagged_array(3)==[[], [], []]
output: def print_jagged_array(size):
      jagged_array = [[] for _ in range(size)]
      print(jagged_array)
