Solution

Sure, here is a Python solution for finding the longest palindromic substring in a string:

def longest_palindrome(s):
    def expand_around_center(s, left, right):
        while left >= 0 and right < len(s) and s[left] == s[right]:
            left -= 1
            right += 1
        return s[left + 1:right]

    if len(s) == 0:
        return ""
    start = 0
    end = 0
