You are given a string s. An awesome substring is a non-empty substring of s such that we can make any number of swaps in order to make it a palindrome.

\n\n

Return the length of the maximum length awesome substring of s.

\n\n

 

\n

Example 1:

\n\n
\nInput: s = "3242415"\nOutput: 5\nExplanation: "24241" is the longest awesome substring, we can form the palindrome "24142" with some swaps.\n
\n\n

Example 2:

\n\n
\nInput: s = "12345678"\nOutput: 1\n
\n\n

Example 3:

\n\n
\nInput: s = "213123"\nOutput: 6\nExplanation: "213123" is the longest awesome substring, we can form the palindrome "231132" with some swaps.\n
