我的代码：

#include <iostream>
#include <cstring>
using namespace std;

int main()
{
    string sa, sb;
    cin >> sa >> sb;
    int a = 1, b = 1;
    for (int i = 1; i <= sa.size(); ++i)
    {
        a = a * (sa[i] - 'A' + 1) % 47;
    }
    for (int i = 1; i <= sb.size(); ++i)
    {
        b = b * (sb[i] - 'A' + 1) % 47;
    }
    if (a == b) cout << "GO";
    else cout << "STAY";
}
