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。DES算法以被应...

多数程序设计语言处理整数的能力是有限的，如C语言中，int类型数据范围是-32767----32767。实际问题的处理过程中往往涉及大整数的运算，如RSA加密算法要求至少64bit的整数，本程序是设计算法实现大整数的加减运算。-majority programming language processing is integral to the limited capacity, such as C language, int data type is the scope-32767---- 32767. Practical problems of the treatment process often involves large integer arithmetic, such as the RSA encryption algorithm requires at least 64-bit integers, the procedure is designed algorithm large integer addition and subtraction operations.

希尔排序算法: 基本思想：将整个无序序列分割成若干小的子序列分别进行插入排序。 序列分割方法：将相隔某个增量h的元素构成一个子序列。在排序过程中，逐次减小这个增量，最后当h减到1时，进行一次插入排序，排序就完成。增量序列一般采用：ht=2t-1,1≤t≤[log2n]，其中n为待排序序列的长度。-Hill sorting algorithm: the basic idea: the whole sequence disorder is separated into a number of small sub-sequences respectively Insertion Sort. Sequence segmentation method: h will be separated by an incremental elements constitute a subset of sequences. In the sort process, the successive decrease of the increment, and finally reduced to one when h when an insertion sort, sort completed. Incremental sequence generally use: ht = 2t-1, 1 ≤ t ≤ [log2n], in which n is the length of sequence to be sorted.
