西江月 · 证明

即得易见平凡，仿照上例显然。留作习题答案略，读者自证不难。

反之亦然同理，推论自然成立，略去过程Q E D ，由上可知证毕。

QED : quod erat demonstrandum (拉丁文)，意思是证明完毕（证毕） 七 律 · 考 试

模拟只会猜题意，贪心只能过样例。数学上来先打表，D P 一般看规律。

组合数学靠运气，计算几何瞎暴力。图论一顿套模板，数论只会G C D 。

子曰：打架用砖乎！ 不宜乱乎，照脸乎，使劲乎， 乎不着，再乎，右手乎完左手乎， 板砖乎断用鞋乎， 岂可一人独乎，有朋一齐乎，不亦乐乎， 乎着，往死里乎，呼不死，还乎， 乎死者，英雄也， 乎不死，拉倒也， 你明乎，不明乎？ 明乎则已，不明乎拿砖照已脸乎！ 一乎则明。

北冥有狗，其名为哈。 外形冷峻，内心傻瓜。 三更半夜，呜呜啊啊。 主人不在，专门拆家。 床单沙发，稀里哗啦； 钢铁横梁，犹如泥巴！ 哈之大，一锅炖不下。 化哈为犬，其名为奇。 奇之大，需要两个烧烤架。 一哈顶三虎， 三哈沉航母， 五哈斗上帝， 十哈创世纪， 百哈毁灭银河系， 千哈宇宙称第一。
