拓展欧几里德算法，控制台程序，求解sa+tb=1中的s,t-Expansion of the Euclidean algorithm, console program, solving sa+ tb = 1 s, t

大数的除法，将大数以数组的形式输入进去并且输出所得的商，可以用于欧几里德扩展算法-Division of large numbers will be entered as an array of large numbers into and outputs the quotient can be used for extended Euclidean algorithm

采用欧几里德距离等分析手段对两个text文档的相似度进行比较。-The similarity of the two text documents were compared using the Euclidean distance method.
