First, do you understand what ste is in mathematical/computing terms?
That is critical to understanding what state variables are?
For example if I say that the state of any object can be represented
by a vector whose values correspond to the collected set of variables
of the object, does that make sense?
If not, we need to go back to consider what state is and why
it is important in computing.
