Description: 有M个敢死队员要炸掉敌人的一碉堡，谁都不想去，排长决定用轮回数数的办法来决定哪个战士去执行任务。如果前一个战士没完成任务，则要再派一个战士上去。现给每个战士编一个号，大家围坐成一圈，随便从某一个战士开始计数，当数到5时，对应的战士就去执行任务，且此战士不再参加下一轮计数。如果此战士没完成任务，再从下一个战士开始数数，被数到第5时，此战士接着去执行任务。以此类推，直到任务完成为止。排长是不愿意去的，假设排长为1号，请你设计一程序，求出从第几号战士开始计数才能让排长最后一个留下来而不去执行任务。-a suicide squad members to blow up an enemy pillboxes, nobody wants to, the platoon leader decided to use the cycle counting methods to decide which fighters to carry out its mandate. If the former soldiers not to complete a task, the soldiers will have to send them a boost. For every fighter is a part, as we were sitting and then casually from a soldier counting began, when several of 5:00, and the corresponding implementation of the soldiers went duties, but the soldiers would no longer participate in this next round of counting. If the soldiers did not complete the tasks, then a soldier began to count, the number of first 5:00, the soldiers proceeded to the task. By analogy, until the job is done. Platoon leader is not willing to go to the assumption that for the 1st Platoon, please des

Description: 一、RSA基本原理
对明文分组M和密文分组C，加密与解密过程如下：
C = POW (M , e) mod n
M = POW(C , d) mod n = POW(POW( M ,e), d) mod n=POW( M,e*d)
其中POW是指数函数，mod是求余数函数。
其中收发双方均已知n，发送放已知e，只有接受方已知d，因此公钥加密算法的公钥为
KU={ e , n},私钥为KR={d , n}。该算法要能用做公钥加密，必须满足下列条件：
1. 可以找到e ，d和n，使得对所有M<n ,POW(M ,e*d)=M mod n .
2. 对所有 M<n,计算POW (M , e)和POW(C , d)是比较容易的。
3. 由e 和n确定d是不可行的
-one, the basic tenets of RSA expressly group M and cipher block C, encryption and decryption process is as follows : C = POW (M, e) mod n = M POW (C, d) mod n = POW (POW (M, e), d) mod n = POW (M, e* d), which is an exponential function POW, mod is the pursuit of the remaining functions. Transceivers which both known n, send e Fang known, the only known recipient d, therefore the public key encryption algorithm for public key e KU = (n), private key for KR = (d, n). The algorithm could be used to be a public key encryption, must meet the following conditions : 1. E can be found, and d n, making all the right M

Description: DES( Data Encryption Standard)算法，于1977年得到美国政府的正式许可，是一种用56位密钥来加密64位数据的方法。
IDEA是International Data Encryption Algorithm 的缩写,是1990年由瑞士联邦技术学院来学嘉X.J.Lai 和Massey提出的建议标准算法称作PES( Proposed Encryption Standard) 。Lai 和Massey 在1992 年进行了改进强化了抗差分分析的能力改称为IDEA 它也是对64bit大小的数据块加密的分组加密算法密钥长度为128位它基于“相异代数群上的混合运算”设计思想算法用硬件和软件实现都很容易且比DES在实现上快的多。IDEA自问世以来，已经经历了大量的详细审查，对密码分析具有很强的抵抗能力，在多种商业产品中被使用。-DES (Data Encryption Standard) algorithm. in 1977 the United States government's official permission, is a key 56 to 64 data encryption methods. IDEA is the International Data Encryption Algorith m initials yes in 1990 by the Swiss Federal Institute of Technology Xuejia Lai X. J. Massey, and the recommendations of the standard operator France called the PES (Proposed Encryption Standard). Lai and Massey in 1992 by improving strengthened against differential analysis of the capacity it renamed IDEA is the size of the 64 bit encryption of the data block encryption algorithm key to a length of 128 based on "different algebra Groups of mixed operation "design algorithm with hardware and software and is easy to achieve than in DES soon have more.
