I'm asked to elaborate on how to solve the problem of finding the longest palindromic substring using the "Expand Around Center" pattern, which was identified in the provided context.
Let me start by understanding the problem:
- Given a string s, I need to find the longest palindromic substring within it.
- A palindrome reads the same forward and backward (like "madam" or "racecar").
- In case of ties (multiple palindromes of the same maximum length), any one of them is a valid answer.
The suggested approach is "Expand Around Center" which is indeed efficient for this problem. Let me outline the solution using bullet points:
