        int len1 = word1.size();
        int len2 = word2.size();
        int max_len = len1 > len2 ? len1 : len2;

        string ret;
        for (int i = 0; i < max_len; i++) {
            if (i < len1) {
                ret += word1[i];
            }

            if (i < len2) {
                ret += word2[i];
            }
