As always there are several ways to do this.
Here's one that uses all 8 digital inputs. The values from the "Boolean Array to Number" will return case numbers 1, 2, & 4 for what you described.

There's more to the DS side than moving a jumper however.
Without any jumper in place, the DS Digital inputs will float around returning random values.
A switch would be handier, but if you do use jumpers, then you'll need
-- one that jumpers signal to 5v
-- another that jumpers signal to ground

Never leave any of the DS pins you are using without a jumper of one type or another in place.
