input: Write a function to minimize a given black box function using scipy.optimize.minimize.
  assert minimize_black_box(lambda x: x ** 2 + 40, (0, 0)) == [0.]
  assert minimize_black_box(lambda x: (x - 5) ** 2, (10,)) == [5.]
  assert minimize_black_box(lambda x: (x + 2) ** 4 + 3, (0,)) == [-2.]
output: from scipy.optimize import minimize
  
  def minimize_black_box(func, x0):
      result = minimize(func, x0)
      return list(result.x)
