Muddleheadedness
We started with going through all the code we already worked with to check whether or not we understood. Luckily we had some printer paper, so printed some files out to annotate by hand. This is how it looked:
We were kind of able to explain all the cryptic looking code, yeay! Relieved we confronted our next challenge: turning a stack upside down.
After … hours of pondering.
The result was overwelming and worth it :)
