input: Write a function to generate a two-dimensional array filled with zeros based on the given number of rows and columns. If either the row or column number is zero, the function should return an empty list.
  def generate_zeros_array(row, col):
      if row == 0 or col == 0:
          return []
      return [[0] * col for _ in range(row)]
  
  assert generate_zeros_array(3, 3) == [[0, 0, 0], [0, 0, 0], [0, 0, 0]]
  assert generate_zeros_array(2, 4) == [[0, 0, 0, 0], [0, 0, 0, 0]]
  assert generate_zeros_array(0, 3) == []
  assert generate_zeros_array(4, 0) == []
  assert generate_zeros_array(1, 1) == [[0]]
output: def generate_zeros_array(row, col):
