Outclassed!
Let's see for the next challenges if I can step up the solution. Furthermore the solution of david are very quick. I wonder if working with the stack could be faster or just be barely faster.

Definitely not outclassed! My solution is too fragile, and it is entirely dependent on the data being exactly as described. My approach used what I call an "assumptive" process (if the given element wasn't a 3, I assumed it must be a 5), which is something I don't consider to be a good programming practice. It just made it easier to have a very small procedure to hand off to DOLIST for this particular problem.
