G - Share the Ruins Preservation xhae
From the problem statement:
"Furthermore, they should minimize the length of such a fence for their budget. If the surrounded areas are vast, expensive costs will be needed to maintain the inside of areas. Therefore, they want to minimize the total preservation cost, i.e. the sum of the areas surrounded by two fences. "

It seems like they need to minimize the length of such a fence, and they want to minimize the sum of areas at then same time. What's the priority between two standards?
