Programming puzzle

This may end up being a total failure. I hope it does not :P

So it is a puzzle for programmers (actually, 2 puzzles).

The first puzzle will be used as filter and solving it will give you access to 3 bundle GAs (no CV requirement) and the second puzzle.
The second puzzle will be a group puzzle (shared answers) with questions related to different programming languages, and solving it will give you access to 1 bundle and 1 no bundle GA (great game IMHO).

I'm not sure how many programmers are here in SG, neither how many enjoy solving puzzles, so I made it a group puzzle to avoid having no solvers. If it turns out to be too easy, there is always time for a future harder puzzle :D

Please post all the second puzzle questions/thoughts/shared breakthroughs in this thread and not in the GAs :D

Without further ado, the puzzle.

I hope you enjoy it.

EDIT: Added languages poll: poll
EDIT2: It seems I forgot about the most used lang according to the poll. My apologies to the java coders U_U
EDIT3: It would we nice if the solvers post here the code used to solve it (for those questions where the answer is not the code itself) :D
