Programming Exercises

Implement the exercises in a programming language of your choice. The only requirement is that the program should be runnable on the Linux machines in the department. Include sufficient explicit output into your program so I can convince myself that the computation actually works.
Submit the source of your program (with an included comment how to run it and your Student ID number) via Moodle. You can also include a Readme file with that information.
Also submit a file with the requested answers (i.e. only the answers to the problems, not the full intermediate output!) together with your code.

Programming exercises will be given on the exercise sheets
