@Constantine____

#include <iostream>
using namespace std;

string a;
int main() {
    int n;
    cin >> n;
    cin >> a;
    for (int i = 0; i < a.size(); i++) {
        if (isalpha(a[i])) { // 检查是否为字母
            char base = islower(a[i]) ? 'a' : 'A'; // 判断是小写还是大写字母
            a[i] = (a[i] - base + n) % 26; // 计算新的字符位置
            if (a[i] < 0) a[i] += 26; // 处理负数情况
            a[i] += base; // 转换回字符
        }
    }
    cout << a;
    return 0;
}
