    483 - Smallest Good Base\.

    Hard

    Given an integer n represented as a string, return the smallest good base of n.

    We call k >= 2 a good base of n, if all digits of n base k are 1's.

    Example 1:

    Input: n = "13"

    Output: "3"

    Explanation: 13 base 3 is 111.

    Example 2:

    Input: n = "4681"

    Output: "8"

    Explanation: 4681 base 8 is 11111.

    Example 3:

    Input: n = "1000000000000000000"

    Output: "999999999999999999"

    Explanation: 1000000000000000000 base 999999999999999999 is 11.

    Constraints:

    • n is an integer in the range <code>3, 10<sup>18</sup></code>.

    • n does not contain any leading zeros.
