String
You are given a string num representing a large integer. An integer is good if it meets the following conditions:
Return the maximum good integer as a string or an empty string "" if no such integer exists.
Note:
Examples
Example 1
Input: num = "6777133339"
Output: "777"
Explanation: There are two distinct good integers: "777" and "333".
"777" is the largest, so we return "777".
Example 2
Input: num = "2300019"
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.
