A string is said to be a palindrome if the string read from left to right is equal to the string read from right to left, for example, abba. The brute force algorithm for this has O(n^3) time complexity but can be improved using dynamic programming. Describe and analyze an algorithm to implement Longest Palindromic Substring (i.e, given a string return the longest possible palindromic substring.) using dynamic programming. Note: return any one such substring if there are multiple longest such substrings are present. Input: s="babad" Output: "bab" Note: "aba is also a valid answer.
