Exercise (warm-up for the next lecture): create a class that retains an integer and prints it as a tetravigesimal number (i.e., base 24). Notice that the alphabet of symbols goes well beyond the traditional “F” of hexadecimal systems. For instance, the tetravigesimal version of 531 (decimal) is M3. For this class, override the following methods:

__init__
__str__
__repr__
