需要吗？？
```cpp
#include<cstdio>
using namespace std;
char k[101],s1[1001];
int main() {
int lk=0 ,ans;
scanf("%s%s",k,s1);
for(int i=0; k[i]!='\0'; i++) if(k[i] >= 'a') k[i] -= 'a',lk++; else k[i] -= 'A',lk++;
for(int i=0; s1[i]!='\0';i++) {
ans = s1[i] - k[i%lk];
if(ans < 'A'|| s1[i] >= 'a' && ans < 'a') ans += 26;
putchar(ans);
}
return 0;
}
```
