The problem is simple: we have a wall outlet which supplies 230V and an apparatus that requires 115V.

Software is always cheaper than hardware (well, most of the time), so we solve this with a program, a Matlab function, to be precise.

Write a program that converts the supplied input voltage to the required output voltage.

If you like this problem, please like it (after solving).

J-G, thanks for the problem. Could you add some more information about expected inputs and outputs? An example and some more tests would be helpful too. If your test suite has exactly one test, it's trivial to write a correct answer.
