Architectural considerations

We created an interface and a simple implementation of it. During the implementation, we discovered that the interface needs other interfaces and methods that are needed to support the algorithm. This usually happens during the architectural design of the code, before implementation. For didactic reasons, I followed the build-up of the interfaces while we developed the code. In real life, when I created the interfaces, I created them all in one step as I have enough experience. I wrote my first quicksort code around 1983 in FORTRAN. However, it does not mean that I hit the bulls-eye with just any problem and come out with the final solution. It just happens that sort is a too well-known problem. If you need to ...
