今天在些写ACM遇到这题有点搞不懂题意，也找不到中文翻译
题目: http://0rz.tw/bY045
尤其是这个rule
- One should not be able to fill a square whose side is less than K using the tile
of (L, W) size. For example, if K = 6, you cannot use (2, 1) tile as you can fill
4x4 square with it. (The king does not like smaller replica of his room with
same size of tile).
以例子来说，意思是K=6不能用 (2, 1) tile，是因为K=4已经用过(2, 1) tile了吗?
example也不是很懂，为什么输入18输出结果会是9 2，我本来以为会是9 1的说...
谢谢各位大大耐心的看完!
