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