哥们 看看我为啥运行错误 凑啊

解题思路:

注意事项:

参考代码:

#include<bits/stdc++.h>

using namespace std;

string s ="abcdefghijklmnopqrstuvwxyz";

char a[30][30];

string s1,s2;

int main()

{

int la,lb,ans;

for(int i = 0 ; i < 26 ;i++)

for(int j = 0 ; j < 26 ;j++)

{

int k = (i+j) % 26;

a[i][j] = s[k];

}

cin >> s1 >> s2;

for(int i = s1.size(),j = 0 ; i <= s2.size() ;i++,j++)

s1[i] = s1[j];

for(int i = 0 ; i <= s2.size() ;i++)

{

ans = 0;

if(s2[i] >= 'A' && s2[i] <= 'Z')

{

s2[i] = s2[i] + 32;

ans++;

}

if(s1[i] >= 'A' && s1[i] <= 'Z')

{

s1[i] = s1[i] + 32;

ans++;

}

for(int k = 0 ; k < 26 ;k++)

{

if(s1[i] == s[k])

{

la = k;

break;

}  

}

for(int j = 0 ; j < 26 ;j++)

{

if(a[la][j] ==s2[i])

{

if(ans == 2)

cout << char(s[j]-32);

else cout << s[j];

break;

}

}

}

return 0;

}
