One extra approach that might work is to work out, with him, the algorithm that solves a tower of Hanoi, a rubics cube, or even a simple puzzle (do a simple puzzle with the picture facing the floor, and you'll quickly end up working like a computer, trying combinations one at a time). One problem here, of course, is that this . This has the benefit of meaning that you can loop through data to reach a result. On the first line we have created what is known as a Method.
