I feel like these are poor choices. * linked lists shouldn't be used anyway. and if they are used, you should use the standard implementation * directly applying fibbonacci is trivial. * sort: This is just a memorisation task, what's the point? (99% of the time, you shouldn't implement your own sort) although, I agree with the open-book approach in the problem solving part.
