解法：

#include<iostream>
#include<vector>
using namespace std;
int main() {int n, m, k;cin >> n;vector<char> man(n);for (int i = 0; i < n; i++) cin >> man[i];cin >> m;vector<char> woman(m);for (int i = 0; i < m; i++) cin >> woman[i];cin >> k;cout << man[(k-1)%n] << " " << woman[(k - 1) % m];return 0;
}
