using namespace std;

int my_stoi(string s) {
    stringstream ss;
    for (auto iter = s.begin(); iter != s.end(); ++iter) {
        if (*iter != ',') ss << *iter;
    }
    int res = stoi(ss.str());
    return res;
}
int main() {
    string a_s, b_s;
    while (cin >> a_s >> b_s) { // 注意 while 处理多个 case
        int a = my_stoi(a_s), b = my_stoi(b_s);
        cout << a + b << endl;
    }
}
// 64 位输出请用 printf("%lld")

删除逗号在调用stoi
