input: Write a python function to convert a list of temperatures from Celsius to Fahrenheit.
  assert convertCelsiusToFahrenheit("0,100") == [32.0, 212.0]
  assert convertCelsiusToFahrenheit("-40,0,100") == [-40.0, 32.0, 212.0]
  assert convertCelsiusToFahrenheit("30,20,10") == [86.0, 68.0, 50.0]
output: def convertCelsiusToFahrenheit(celsius_string):
      celsius_list = map(float, celsius_string.split(','))
      fahrenheit_list = [(c * 9/5) + 32 for c in celsius_list]
      return fahrenheit_list
