@丸子粥 第一次循环

(sentence.substr(i-k-1,k)->(sentence.substr(0-0-1,k)->(sentence.substr(-1,k)

哦豁，完蛋

1. a有可能炸掉
2. getline不好

@Ofnoname cin不能输入空格啊 我太难了

=================================== 改成这样了 但是还是不对 但是结果还是跟原来一样的

by gx123 @ 2019-08-12 12:54:42

最好改成long long

by gx123 @ 2019-08-12 12:55:12

我就是用int然后就80

by jijidawang @ 2019-12-07 17:31:39

开头去0
