先生成两个二进制整数文件f1,f2。然后将f1和f2按照下面规则合并成二进制文件。 f3：假设f3中的数据为x，则x存在于f1中但不存在于f2中，或者x存在于f2中， 但不存在于f1中。即f3中的数据是由存在于f1或f2但不同时存在于f1和f2的数组成。-Mr. into two binary integer file f1, f2. Then f1 and f2 are merged into a binary file according to the following rules. f3: f3, the data assume that for x, then x exists in f1 but not f2 in x exists at f2, but it does not exist in f1. F3, the data exist in the number of f1 or f2, but not present in the f1 and f2.
