1.编写一个JSP程序，计算1！+2！+3！+4！+5！，并显示出结果。
要求先声明计算阶乘的方法，再调用该方法，最后在页面上输出结果。
2.2、在JSP页面中静态包含文件。
要求程序包含两个文件，主文件静态包含一个能够计算1到1000内的完数的页面。
（如果一个正整数刚好等于它的真因子之和，这样的正整数为完数，例如，6=1+2+3，因此6就是一个完数。
）3.动态包含页面并传递数据。
要求程序包含两个文件，主文件（actioninclude）加载次文件（redirection），并将随机产生的50~100之间的数据传递给它，并且在页面上显示两个信息：该数据和这个数据的平方根。
进阶要求，把动态包含改为动态重定向，比较两者之间的区别。
4.本题包括4个JSP程序，one.jsp、two.jsp、three.jsp、error.jsp。
one.jsp具体要求如下：要求one.jsp页面有一个表单，用户使用该表单可以输入一个1至100之间的整数，并提交给下一个页面；
如果输入的整数在50至100之间（不包括50）就转向three.jsp，如果在1至50之间就转向two.jsp；
如果输入不符合要求就转向error.jsp。
要求forward标记在实现页面转向时，使用param子标记将整数传递到转向的two.jsp或three.jsp页面，将有关输入错误传递到转向的error.jsp页面two.jsp、three.jsp和error.jsp的具体要求如下：要求two.jsp和three.jsp能输出one.jsp传递过来的值，并显示一幅图像，该图像的宽和高刚好是one.jsp页面传递过来的值。
error页面能显示有关抛出的错误信息。
（程序中使用的图片，可自行准备）。

1、输入层的每个节点，都要与的隐藏层每个节点做点对点的计算，计算的方法是加权求和+激活2、利用隐藏层计算出的每个值，再用相同的方法，和输出层进行计算。
3、隐藏层用都是用Sigmoid作激活函数，而输出层用的是Purelin。
这是因为Purelin可以保持之前任意范围的数值缩放，便于和样本值作比较，而Sigmoid的数值范围只能在0~1之间。
4、起初输入层的数值通过网络计算分别传播到隐藏层，再以相同的方式传播到输出层，最终的输出值和样本值作比较，计算出误差，这个过程叫前向传播(ForwardPropagation)。
误差信号反向传递过程

Xmodem协议传输由接收程序和发送程序完成。
先由接收程序发送协商字符，协商校验方式，协商通过之后发送程序就开始发送数据包，接收程序接收到完整的一个数据包之后,按照协商的方式对数据包进行校验。
校验通过之后发送确认字符，然后发送程序继续发送下一包；
如果校验失败，则发送否认字符，发送程序重传此数据包。
Xmodem协议是由WardChritensen于70年代提出并实现的，传输数据单位为信息包。
Xmodem协议一般支持128字节的数据包，并且支持校验和、CRC两种校验方式。

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
