Description: 验证：2000以内的正偶数都能够分解为两个素数之和(即验证歌德巴赫猜想对2000以内的正偶数成立)。
*问题分析与算法设计
为了验证歌德巴赫猜想对2000以内的正偶数都是成立的，要将整数分解为两部分，然后判断出分解出的两个整数是否均为素数。若是，则满足题意；否则重新进行分解和判断。
程序中对判断是否为素数的算法进行了改进，对整数判断“用从2开始到该整数的一半”改为“2开始到该整数的平方根”。原因何在请自行分析。

Description: 验证卡布列克运算。任意一个四位数，只要它们各个位
上的数字是不全相同的，就有这样的规律：
1)将组成该四位数的四个数字由大到小排列，形成由这四个
数字构成的最大的四位数；
2)将组成该四位数的四个数字由小到大排列，形成由这四个
数字构成的最小的四位数(如果四个数中含有0，则得到的数不足
四位)；
3)求两个数的差，得到一个新的四位数(高位零保留)。
重复以上过程，最后得到的结果是6174，这个数被称为卡布
列克数。-certification Roman computing. A four-digit arbitrary, as long as they all place on the same figure is incomplete, this is the law : a) the composition of the four four-digit figures with 7,10,13, formed by four of the greatest figures of the four-digit; 2) The composition of the four four-digit figures headed arranged by the formation of the four figures constitute the smallest of the four-digit (if 4 contains a few 0, then the less than 4); 3) 2 for the number of poor, received a new four-digit (high-reservations). Repeat the above process, the final result is 6,174, a figure known as the Roman few.

Description: 棋盘填充程序残缺棋盘的问题是：要求用三格板（triominoes）覆盖残缺棋盘（如图1-2所示）。在此覆盖中，两个三格板不能重叠，三格板不能覆盖残缺方格，但必须覆盖其他所有的方格。在这种限制条件下，所需要的三格板总数为(22k-1)/3。可以验证(22k-1)/3是一个整数。k为0的残缺棋盘很容易被覆盖，因为它没有非残缺的方格，用于覆盖的三格板的数目为0。当k=1时，正好存在3个非残缺的方格，并且这三个方格可用图1-2中的某一方向的三格板来覆盖。-chessboard filled with incomplete procedures chessboard question is : They want the three grid plate (triominoes) chessboard incomplete coverage (as shown in Figure 1-2).

In such conditions, the required three the total number of grid plate (22k-1) / 3. Can certification (22k-1) / 3 is an integer. K 0 chessboard of the deterioration can easily be covered, because it does not non-ramshackle box for coverage of the three grid plate number of 0.

Description: Wealsh 游戏更新器(网吧版)
本次更新主要为:
采用文件修改时间验证更新文件（之前是CRC32，速度受不了了）。
在服务端生成的更新文件列表内容如：
\\accounts\\account.dat|317!2005-11-23（文件路径|大小!修改时间）。
文件对比准确率为99.99%，即能精确找出需要更新的文件。
当每下载完一个文件后将其修改时间更改成与服务器里面的文件一至。因此不用理会客户机与服务器的系统时间是否一样，都能找出需要更新的游戏文件。哈哈，其实这些都比较简单的...
速度大大提高了！
服务器最好装上win2003吧，利用IIS6，其下载速度真的不错!能达到10M/s。-Wealsh game update (Internet edition) of this major update : using modified certification document updates (CRC before, speed straw). In the service-generated content updated list of documents such as : \\ accounts \\ account.dat | 317! 2005-11-23 (document Road Drive | Size! modified time). Document Comparison accuracy rate of 99.99%, that can pinpoint the need to update the document. When each download a document will be revised as time changes with the server inside a document to. It does not matter client and server systems timing just as able to identify the need to update the documents game. Haha, in fact these are relatively simple ... greatly increased the speed! The best server installed on Win2003 bar, the use of IIS6. download speed is really good! achieve 10M / s.
