Given a string S, find the longest palindromic substring in S. Substring of string S: S[ i . . . . j ] where 0 ≤ i ≤ j < len(S). Palindrome string: A string which reads the same backwards. More formally, S is palindrome if reverse(S) = S. Incase of conflict, return the substring which occurs first ( with the least starting index ).
Example 1:
Input:
S = "aaaabbaa"
Output:
aabbaaExplanation:
The longest palindrome string present in
the given string is "aabbaa".
Your Task:
You don't need to read input or print anything. Your task is to complete the function longestPalindrome() which takes string Sas input parameters and returns longest pallindrome present in string.
Expected Time Complexity: O(|S|2) Expected Auxiliary Space: O(1)

Avoid using static/global variables in your code as your code is tested
against multiple test cases and these tend to retain their previous values.
Passing the Sample/Custom Test cases does not guarantee the correctness of code.
On submission, your code is tested against multiple test cases consisting of all
possible corner cases and stress constraints.
