今天刚考这题

#include<bits/stdc++.h>
using namespace std;
int main(){
    int n;
    string a;
    cin>>n>>a;
    for(int i=0;i<n;i++){
        for(int j=0;j<a.size();j++){
            if(a[j]=='z'){
                a[j]='a';
            }else{
                a[j]+=1;
            }
        }
    }
    cout<<a;
    return 0;
}
