Problem of the day
1. Split 'S' into three non-empty substrings such that each character of 'S' should present in exactly one substring.
2. Create a new string by concatenating 1st and 3rd parts.
Let 'N' = 6, 'S' = "abccba".
Three substrings are "ab", "cc", and "ba" and by concatenating 1st and 3rd parts we get "abba" which is a palindrome.
So our answer is 1.
First-line contains an integer 'T', which denotes the number of test cases.
For every test case:-
First-line contains an integer 'N', denoting the length of the string 'S'.
Second-line contains a String 'S', which consists of 'N' lowercase English letters.
For each test case, Return 1 if you can make this new string a palindrome otherwise return 0.
You don’t need to print anything. Just implement the given function.
1 <= 'T' <= 10
3 <= 'N' <= 10^5
'S' consists of 'N' lowercase English letters.
The Sum of 'N' overall test cases does not exceed 10^5.

First test case:-
It can be proven that we cannot make the new string a palindrome.
So our answer is 0.
Second test case:-
Three substrings are "zzz", "z", and "z" and by concatenating 1st and 3rd parts we get "zzzz" which is a palindrome.
So our answer is 1.
