Write a function called pe21 that takes two input arguments indicating the current time: hr for hours and min for minutes. The function checks whether the two inputs can in fact represent time according to the international format. That is, it needs to check that they are both positive integer scalars and hr is between 0 and 23 inclusive and min is between 0 and 59 inclusive. The function returns a logical value: true if the input arguments satisfy these rules and false otherwise.
