+## 思路
+
+按照题意计算即可。
+
+## 代码
+
+```cpp
+#include <bits/stdc++.h>
+
+using namespace std;
+
+int main() {
+    int us = 1, zs = 1;
+    string a, b;
+    getline(cin, a);
+    getline(cin, b);
+    for (int i = 0; i < 7; i++) {
+        if (a[i] <= 0) break;
+        else us *= a[i] - 64;
+    }
+    for (int i = 0; i < 7; i++) {
+        if (b[i] <= 0) break;
+        else zs *= b[i] - '@';
+    }
+    us %= 47;
+    zs %= 47;
+    if (us == zs) cout << "GO" << endl;
