本题为博弈论题,稍微思考一下即可。

AC code:

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

int main() {
    long long a, b;
    cin >> a >> b;
    long long sg_a = a % 3;
    long long sg_b = b % 3;
    if ((sg_a ^ sg_b) != 0) {
        cout << "2se" << endl;
    } else {
        cout << "tyw" << endl;
    }
    return 0;
}
