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

\n\n

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

\n\n

Example 1:

\n\n
\nInput: n = "13"\nOutput: "3"\nExplanation: 13 base 3 is 111.\n
\n\n

Example 2:

\n\n
\nInput: n = "4681"\nOutput: "8"\nExplanation: 4681 base 8 is 11111.\n
\n\n

Example 3:

\n\n
\nInput: n = "1000000000000000000"\nOutput: "999999999999999999"\nExplanation: 1000000000000000000 base 999999999999999999 is 11.\n
