input: Write a function to print every number from 0 to 10, with each number being multiplied by 2.
  assert print_multiplied() == "0 2 4 6 8 10 12 14 16 18 20"
  assert print_multiplied() == "0 2 4 6 8 10 12 14 16 18 20"
output: def print_multiplied():
      result = " ".join(str(i * 2) for i in range(11))
      return result
