Steve RumsbyI’m very glad you mentioned Project Euler, because I have now signed up and I’m starting to work through solutions to some of the problems, also using ABAP. However, I have discovered this on the Project Euler “About” page:

I wonder, therefore, if you should reconsider publishing solutions here? I confess I was considering doing the same, particularly as I was planning on using some non-traditional ABAP techniques (object orientation, functional programming, lazy evaluation, etc.) as I did in this blog – Object-oriented Sieve of Eratosthenes – and I think such things might be educational for others. Now I’ll continue working through the Project Euler problems but I’ll find another source of inspiration for my non-traditional ABAP blogs.

Steve.

Luca MasiniPost authorHi Steve,

thank you for your feedback.

I will publish only some solution to very old problem (the one for which the forum is closed).

For other I will use the Project Euler forum that is accessible after you have solved a particular problem.

Luca.

Steve RumsbyIt is a shame, really, because there are some interesting problems there. Producing elegant solutions to them is a good way to learn, and having other people comment on your solutions and suggest alternative mechanisms is even better. As I said, I was going to do exactly the same as you until I read that. But it seems only right to respect their wishes.

I hadn’t noticed that the discussion forums for some problems are closed – I guess I haven’t solved any of those yet!
