input: Write a function to construct and print a jagged array of a given size without any values. The function should initialize an array with the given size and populate each element with an empty sub-array. If the given size is zero, print an empty array.
  
  def print_jagged_array(array_size):
      # Initialize a jagged array with the given size
      array = [[] for _ in range(array_size)]
      
      # Print the output array
      print(array) 
  
  if __name__ == "__main__":
      array_size = 4
      print_jagged_array(array_size)
  assert print_jagged_array(4) == [ [], [], [], [] ]
  assert print_jagged_array(0) == [ ]
output: def print_jagged_array(array_size):
      array = [[] for _ in range(array_size)]
      print(array)
