Minimum Length of Anagram Concatenation(LeetCode 3138):

Problem

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.

 

Constraints:

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