三分巧克力
« on: 七月 14, 2004, 09:47:25 am »
Prof.10K 沉溺于电子游戏,还想拉大伙儿都下水。。。
偶也来出一题:分巧克力。

一矩形巧克力(2m x 2n),  左上角和右下角的一小块已被吃了。问:能否将剩余的 (2m x 2n - 2) 块分成 (2 x m x n - 1) 个“日”字型的小块?Why?

Yes, I like that game very much and recommended to many people already. It is kind of like solving math problem with many constraints.

About your problem, this is one of the classics. It fit into this forum perfectly well. If you think in the right approach, it is so easy, but if don't think in that approach, it seems so hard.

Hint: consider a chess board.

Prof.10K:
Good hint. I think you know the answer.
I am waiting for your next "weekly problem". Don't have time to play computer games (especially at work). It takes too much time in front of the screen, literally. :wink:
