DES(Data Encrypton Standard) 算法的实现网上已经有很多,本人在此讲述的是在DES算法加密过程中如何查看16迭代过程中生成的Ki,Li,Ri,Fi,Si等,这样可以当做一个DES加密对照器,这样可以方便的发现你在加密过程中出现的错误!

* This a software code module for a time-of-day clock object. * The clock may be fixed 12-hour, fixed 24-hour, or dynamically * configurable between these two types. Clock data can be accessed * as a binary number representing the number of minutes since midnight * or a BCD number formatted according to the time-of-day description * in the TIME module 0404x. The functions work with time-of-day values * which conform to normally accepted clock values of 1:00 to * 12:59 BCD / 0 to 719 binary for a 12-hour clock or clock values * 00:00 to 23:59 BCD / 0 to 1439 binary for a 24-hour clock. On power-up * the clock is 12:00 BCD / 0 binary for a 12-hour or dynamically * configurable clock, or 00:00 BCD / 0 binary for a 24-hour clock.

HDOJ ACM input:The input consists of T test cases. The number of test cases ) (T is given in the first line of the input. Each test case begins with a line containing an integer N , 1<=N<=200 , that represents the number of tables to move. Each of the following N lines contains two positive integers s and t, representing that a table is to move from room number s to room number t (each room number appears at most once in the N lines). From the N+3-rd line, the remaining test cases are listed in the same manner as above.
