input: Write a python function to generate a random board configuration of a given size.
  assert len(get_board_config(5)) == 5 and len(get_board_config(5)[0]) == 5
  assert all(cell in [0, 1] for row in get_board_config(3) for cell in row)
  assert len(get_board_config(0)) == 0
output: import random
  
  def get_board_config(size):
      return [[random.choice([0, 1]) for _ in range(size)] for _ in range(size)]
