Dynamic Programming; Brute Force. When given a string, and asked to find the longest palindromic substring, a nested approach that considers every substring and individually checks if it is a palindrome is an idea that would definitely strike. It is a time consuming O(n^3) approach. The implementation is … See more When given a string, and asked to find the longest palindromic substring, a nested approach that considers every substring and individually checks if it is a palindrome is an idea that would definitely strike. It is a time consuming … See more The algorithm might seem very simple, we run two loops i, from 0 to the size of the string, and j that starts from i.
