Assuming the following circuits have been implemented:

• A counter circuit that counts from 1 to 9.

• A seven-segment display decoder circuit.

How should you design to display the counting result on the seven-segment display?

This section provides a feasible implementation method. Note: There isn't a unique implementation method, you can try designing it yourself.

Specific specifications:

Let the seven-segment display generate numbers 1 through 9 in a loop. The number of digits on the seven-segment display can be controlled through sliding switches (from all off to all eight digits).
