There is a blank cd. You are given two colours of paint, say black and white . A sensor can recognize the colour painted on the disc and produce an output. Paint the disc in a way such that you can find the direction of rotation by looking at the output.

Please try to solve this problem.If not I’ll mail u guyz later.
