poj 3941 Hideyuki is allowed by his father Ujisato some 1000 yen bills every month for his pocket money. In the first day of every month, the number of bills is decided as follows. Ujisato prepares n pieces of m-sided dice and declares the cutback k. Hideyuki rolls these dice. The number of bills given is the sum of the spots of the rolled dice decreased by the cutback. Fortunately to Hideyuki, Ujisato promises him to give at least one bill, even if the sum of the spots does not exceed the cutback. Each of the dice has spots of 1 through m inclusive on each side, and the probability of each side is the same. In this problem, you are asked to write a program that finds the expected value of the number of given bills.

chemcad简介 1.CHEMCAD软件概述： CHEMCAD系列软件是美国Chemstations公司开发的化工流程模拟软件。使用它，可以在计算机上建立与现场装置吻合的数据模型，并通过运算模拟装置的稳态或动态运行，为工艺开发、工程设计、优化操作和技术改造提供理论指导。 1.1使用CHEMCAD可以做的工作主要有以下几项： A.设计更有效的新工艺和设备使效益最大化 B.通过优化脱瓶颈改造减少费用和资金消耗 C.评估新建旧装置对环境的影响 D.通过维护物性和实验室数据的中心数据库支持公司信息系统 1.2CHEMCAD中的单元操作： CHEMCAD提供了大量的操作单元供用户选择，使用这些操作单元，基本能够满足一般化工厂的需要。 对反应器和分离塔，提供了多种计算方法。ChemCAD可以模拟以下单元操作： 蒸馏、汽提、吸收、萃取、共沸、三相共沸、共沸蒸馏、三相蒸馏、电解质蒸馏、反应蒸馏、反应器、热交换器、压缩机、泵、加热炉、控制器、透平、膨胀机等50多个单元操作。 (err)

CA认证系统中使用最广泛的证书载体是USBKEY，国内各大产商一般是使用CSP服务来提供加解密服务。这个例子是2048位的RSA数字签名与验证签名，使用厂家自带的csp来实现（若下载者没有安装任何USBKEY的驱动，可将代码中的TEST_CSP_NAME宏改为NULL 即调用微软自带的csp），编译环境VC6.0。(CA authentication system is the most widely used carrier certificate in USBKEY, the major domestic producers are generally use of CSP service to provide encryption services. This example is a 2048- bit RSA digital signature and verifying signature, use the manufacturer s own CSP to achieve (if downloaders not install any driver USBKEY, TEST_CSP_NAME macros in your code can be changed to NULL is called Microsoft s own CSP), the compiler environment VC6.0.)

此工具用来检查DLL EXE OCX 等的依赖性，非常有用。当你OCX DLL注册不了时，请用这个检查试一下。 (This tool is used to check such as the DLL EXE OCX dependence, very useful. When you can not register OCX DLL, please try to use this check.)
