FJ's farm is a 5 x 5 grid. The elevations in the first row are 0, 0, 0, 3, and 3, and so on.
样例：FJ的农田可以视为一个5\*5的网格。第一行的高度是0，0，0，3，3，以此类推。
A tractor of cost 3 is capable of moving between elevation 0 and elevation 3, so it can visit the block of cells at zero elevation as well as the block of cells at elevation 3. Together, these represent at least half of FJ's farm.
一个三块钱（滑稽）的拖拉机可以在高度为0和3的网格之间移动，所以它可以通过0和3高度的网格单元。加起来，这占了FJ农田的至少1/2。

FJ would like to pay enough for his tractor so that, starting from some grid cell in his field, he can successfully drive the tractor around to visit at least half the grid cells in the field (if the number of total cells in the field is odd, he wants to visit at least half the cells rounded up). Please help him compute the minimum cost necessary for buying a tractor capable of this task.
FJ愿意花足够的钱买拖拉机，使拖拉机从他土地中的某个网格单元出发，他开拖拉机可以成功到达他田地中至少一半的网格单元（其实括号里的是废话）。请帮助FJ（为什么这次没有奶牛）编程计算完成目标所需的最小的买拖拉机的价格
