Hi Mikael,

Thank you for sharing the solution you found!

Your definitions suit me too, but in any case I’ll play with your code to see whether using the concept of « coupling » between each exercise and its solution (or hint, if one adds them) could allow the creation of an automatic interaction link between them, so that one can remove the necessity of adding manually a reference to each exercise and each solution.

Best regards: OK
