Longest Palindromic Substring Solution – Python LeetCode
The goal is to create all palindromes of even and odd lengths while keeping track of the longest palindrome seen so far. To make a palindrome with an odd length, For lengthier palindromes, fix a centre and expand in both directions, i.e. fix I (index) as the centre and two indices as i1 = i+1 and i2 = i-1. If i1 and i2 are equal, reduce i2 and raise i1 to get the maximum length.
