Longest Palindromic Substring – Part 2

The video tutorial explains how to solve the longest palindrome substring problem. It begins with initializing variables and setting up a loop to iterate through the string. A helper function is created to check for palindromes by expanding around potential centers. The solution is implemented and tested, showing a runtime of 48 milliseconds. The tutorial concludes with a complexity analysis, highlighting the time complexity as O(n^2) and space complexity as O(1).
