Hi, David. Thanks for the response!

As far as I understand, since I'm using `-std=c++11` option, it SHOULD be
right. Anyway, I tried your suggestion, and it did not work (Same problem)
:( I'll leave the link here just for reference:

Good news is... After trying a bit more, I managed to make the code work.
Turns out it as a missing `#include <vector>`. I don't know why the first
example works, (Now I believe none of them should work). Here's the working
example: https://pastebin.com/Setuw9cF

Does anyone knows why the first example was working, even with the missing
