根据规则去计算，正确的isbn码输出right，错误的输出正确的

第二个题目有讲

@yuanshanlishu

第一个样例： 067082162

(1\times0+2\times6+3\times7+4\times0+5\times8+6\times2+7\times1+8\times6+9\times2) \bmod 11 = 4

4=4

@haijun_ ok 这个我知道了谢谢

by riki1230 @ 2023-04-17 19:58:13

@ydq1101 也就是说当前位数乘以当前数字的总和模11与验证码相等就对是吗？

by InversionShadow @ 2023-04-17 20:00:22

@yuanshanlishu 是的
