Given an alphanumeric string s, return the second largest numerical digit that appears in s, or -1 if it does not exist.

\n\n

An alphanumeric string is a string consisting of lowercase English letters and digits.

\n\n

 

\n

Example 1:

\n\n
\nInput: s = "dfa12321afd"\nOutput: 2\nExplanation: The digits that appear in s are [1, 2, 3]. The second largest digit is 2.\n
\n\n

Example 2:

\n\n
\nInput: s = "abc1111"\nOutput: -1\nExplanation: The digits that appear in s are [1]. There is no second largest digit. \n
