here is another great puzzle
1) Start with VG
2) If you possess a string whose last letter is G, you can add an C at the end
3) If you have Vx you can add Vxx to your collection
Example: (VGC => VGCGC)
4) if you have GGG you can replace that with C
5) If you have CC you can drop it
6) Find a way to get VC
