input: Write a function to generate a jagged array of a given size and print it without any values. The function should initialize the jagged array with empty sub-arrays corresponding to the given size.
  
  def print_jagged_array(array_size):
      # Initialize a jagged array with the given size
      array = [None] * array_size
      
      # Populate the array with empty arrays
      for i in range(array_size):
          array[i] = []
      
      # Print the output array
      print(array)
  
  if __name__ == "__main__":
      array_size = 4
      print_jagged_array(array_size)
  
  assert print_jagged_array(4) == None   # This will print [[], [], [], []]
  assert print_jagged_array(2) == None   # This will print [[], []]
output: def print_jagged_array(array_size):
      array = [[] for _ in range(array_size)]
      print(array)
