You are given a string s, which is known to be a concatenation of anagrams of some string t.

Return the minimum possible length of the string t.

An anagram is formed by rearranging the letters of a string. For example, "aab", "aba", and, "baa" are anagrams of "aab".

 

Example 1:

Input: s = "abba"

Output: 2

Explanation:

One possible string t could be "ba".

Example 2:

Input: s = "cdef"

Output: 4

Explanation:

One possible string t could be "cdef", notice that t can be equal to s.

Example 2:

Input: s = "abcbcacabbaccba"

Output: 3

 

Constraints:

  • 1 <= s.length <= 105
  • s consist only of lowercase English letters.

Hints

Hint 1
The answer should be a divisor of s.length.
Hint 2
Check each candidate naively.
