Most engineering systems has redundancy. That is, an engineering system has more than is required to accomplish its purpose. Consider a nuclear reactor whose temperature is monitored by three sensors. An alarm should go off if any of the sensors reading disagree. Write a function with three input arguments that contain the temperature readings from each sensor; and one output argument that should be a string with the word alarm if any of the sensors readings disagree by more than 10 degrees, otherwise the output should say normal. Send the output argument to the command window.
