[erlang-questions] concentate solution well ??

The goal is to solve the problem as stated such that it would work for
*any* example, not just that one. It's very easy to come up with an example
that does not work with your implementation.
Perhaps you should read the source for the lists module, and take the time
to try and understand it.
