今天逛论坛看到一道非常有意思的题目“由杀人游戏写程序分析”
原题如下：
某地发生了一起谋杀案，警察通过排查确定杀人凶手必为4个嫌疑犯中的一个。以下为4个嫌疑犯的供词。
A说：不是我。
B说：是C。
C说：是D。
D说：C在胡说。 已知3个人说了真话，1个人说的是假话。请根据这些信息，写一个程序来确定到底谁是凶手 。
这是一道非常简单的逻辑思维题，正常人都可以推理出谁是凶手，但是如果叫你写一个程序来判断谁是凶手呢？你能写出来吗？或许你能写出来，但你写的程序一定是最好的吗？
事实上很多人都是写不出来的，因为不懂得把自己所想的用程序表示出来，而一些能够写出来的，却把程序写得过于复杂。昨天一个同学跟我说了这样一句话“程序是最公正的，能够运行出你想要结果的程序就是对的”。我想了一下，是对的。但不够完美，真正的程序员应该追求用最完美的程序来运行出想要的结果。
答案揭晓了，(*^__^*) ，你一定会惊叹作者的聪明才智。
<?php
$men = array ( 'A','B','C','D' ) ; //四个嫌疑犯
foreach ( $men as $man ) //逐个判断。
{
if( ($man!='A')+($man=='C')+($man=='D')+($man!='D') == 3 ) //有三个人说的话是真的话条件成立
echo $man . ' is the killer.' ;
}
?>This is perfect program。

I have really learned newer and more effective things by your weblog. One other thing I would like to say is newer computer system operating systems often allow far more memory to be used, but they in addition demand more memory space simply to operate. If an individual's computer can't handle extra memory and also the newest program requires that memory increase, it usually is the time to buy a new Laptop. Thanks

Cycling jerseys generally have pockets which are on the rear; heavy items can get in the way if the pockets are on the front of the shirt. Some have multiple pockets, some have zips on the pockets, which are the ones I prefer as things don’t fall out of them!

Thanks for your posting. One other thing is that if you are advertising your property on your own, one of the challenges you need to be mindful of upfront is just how to deal with property inspection reviews. As a FSBO vendor, the key about successfully shifting your property plus saving money with real estate agent commission rates is knowledge. The more you already know, the better your sales effort will probably be. One area in which this is particularly vital is reports.
