#include <bits/stdc++.h>
using namespace std;

int main() {
    string a="abcdefghijklmnopqrstuvwxyz";
    string b=a;
    reverse(b.begin(),b.end());
    string s;
    while(cin>>s){
        for(auto &x:s){
            x=b[a.find(x)];
        }
        cout<<s<<endl;
    }
}

限制这题解题速度的可能就是键盘的熟悉程度了吧
