input: Write a function to create and print a jagged array with a specific size, containing empty arrays in each position. If no size is provided, an empty array should be printed.
  
  def print_jagged_array(array_size=0):    
      # Initialize a jagged array with the given size
      array = [[] for _ in range(array_size)]
      
      # Print the output array
      print(array)

output: def print_jagged_array(array_size=0):
