An integer is **good** if it meets the following conditions: It is a **substring** of `num` with length `3`. It consists of only one unique digit. Return _the **maximum good **integer as a **string** or an empty string _`\"\"`_ if no such integer exists_. Note: A **substring** is a contiguous sequence of characters within a string. There may be **leading zeroes** in `num` or a good integer. **Example 1:** ``` **Input:** num = \"6**777**133339\" **Output:** \"777\" **Explanation:** There are two distinct good integers: \"777\" and \"333\". \"777\" is the largest, so we return \"777\". ``` **Example 2:** ``` **Input:** num = \"23**000**19\" **Output:** \"000\" **Explanation:** \"000\" is the only good integer. ``` **Example 3:** ``` **Input:** num = \"42352338\" **Output:** \"\" **Explanation:** No substring of length 3 consists of only one unique digit. Therefore, there are no good integers. ``` **Constraints:** `3 <= num.length <= 1000` `num` only consists of digits.",8  "test_case": [9    {10      "label": "Example 1",11      "input": "num = \"6 777 133339\"",12      "output": "\"777\" "13    },14    {15      "label": "Example 2",16      "input": "num = \"23 000 19\"",17      "output": "\"000\" "18    },19    {20      "label": "Example 3",21      "input": "num = \"42352338\"",22      "output": "\"\" "23    }24  ],25  "constraints": [26    "It is a substring of num with length 3.",27    "It consists of only one unique digit.",28    "A substring is a contiguous sequence of characters within a string.",29    "There may be leading zeroes in num or a good integer.",30    "3 <= num.length <= 1000",31    "num only consists of digits."32  ],33  "python_template": "class Solution(object):\n    def largestGoodInteger(self, num):\n        \"\"\"\n        :type num: str\n        :rtype: str\n        \"\"\"\n        ",34  "java_template": "class Solution {\n    public String largestGoodInteger(String num) {\n        \n    }\n}",35  "metadata": {36    "func_name": "largestGoodInteger"37  }38}
