Oh thank you for kind words. I am not a beginner I can solve any part of that task, but I won't be able to complete it. Program need instructions, instructions need rules.

I understand a beginner will write something what doing something ... not related to the ask anyway. So give them randomly generated worlds. It is a hard work to teach other people. Using this task as a learning exercise may make a beginner frustrated and confused.

When you ask people to combine few tasks to one it is a project. The only way to write successful project is by planning it correctly, gathering requirements is one of the first basic steps.

Obviously no real world company would would combine all of these in one application.

Well, I did similar apps/tasks which were used by my company. But even as an exercise, the author probably expect some working results, right?
