猜你想要：

line 42 之前的修改，后面不会改

inline int makd(string s) {
    int l = s.size();
    int px = 1;
    int turn = 0;
    for (int i = l - 1; i >= 0; i--) {
        turn += (s[i] - '0') * px;
        px *= 10;
    }
    return px;
}

inline bool isitd(string s) {
    for (int i = 0; i < s.size(); i++) {
        if (!(s[i] <= '9') || !(s[i] >= '0')) {
            return 0;
        }
    }
    return 1;
}
