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: 2Explanation:One possible string t could be "ba".Example 2:Input: s = "cdef"Output: 4Explanation:One possible string t could be "cdef", notice that t can be equal to s. Constraints:1 <= s.length <= 105s consist only of lowercase English letters.

Solution
To solve this problem, we can use the concept of sets in Python. A set is an unordered collection of unique elements.
Here are the steps to solve this problem:
-
Convert the string
sinto a set. This will remove all duplicate characters because sets only contain unique elements. -
Get the length of the set. This will give us the minimum possible length of the string
tbecausetcan be any anagram ofs.
Here is the Python code that implements these steps:
def min_length(s):
return len(set(s))
This function works by converting the string s into a set and then returning the length of the set. The length of the set is the minimum possible length of the string t because t can be any anagram of s.
For example, if s = "abba", the set of s is {'a', 'b'}, and the length of the set is 2. Therefore, the minimum possible length of the string t is 2.
If s = "cdef", the set of s is {'c', 'd', 'e', 'f'}, and the length of the set is 4. Therefore, the minimum possible length of the string t is `4

Given a string S. the task is to determine if there exists another string that is an anagram of S.An anagram is a word or phrase formed by rearranging the letters of another word or phrase. For example "seekg" is an anagram of "geeks".Example 1:Input: S = "ab"Output: YESExplanation:The string "ba" is not identical to S and is an anagram of S
Given two strings A and B, find the minimum number of characters that need to be deleted from these 2 strings to make them anagrams of each other.
Given 2 strings, check if they are anagrams. An anagram is a rearrangement of the letters of one word to form another word. In other words, some permutations of string A must be the same as string B.Input FormatThe first line of input contains T - the number of test cases. It's followed by T lines, each line containing 2 space-separated strings.Output FormatFor each test case, print True/False, separated by a new line.Constraints10 points1 <= T <= 1001 <= len(S) <= 103'a' <= S[i] <= 'z'40 points1 <= T <= 1001 <= len(S) <= 105'a' <= S[i] <= 'z'ExampleInput4iamlordvoldemort tommarvoloriddleb hstop posthi heyOutputTrueFalseTrueFalse
