OK, now house cleaning.

Write a function showOneConfig() that pretty much holds everything after this line:

```auto
    String binaryk = (binary(k, 9));

```

It gets the parameters showOneConfig ( binaryk , x, y );

Show this code here.

Then make a for-loop inside showOneConfig for each char so it’s more DRY.

(Or make 2 nested for-loops.)

Great work!

I am pleased to see that you worked through all of this.

I learned along the way as well! All that [bit fiddling](https://en.wikipedia.org/wiki/Bit_manipulation) I did in the past is still part of me.

Every time you look at your code you will see something new to tweak.

Enjoy the journey!
