Longest Palindromic Substring

Explore how to solve the longest palindromic substring problem by developing a clear approach to identify palindromes within a string. Understand constraints and implement an optimal O(n²) time and space solution to strengthen your coding interview skills.

Statement

Given a string s, return the longest palindromic substring in s.

Note: If there are multiple valid palindromic substrings of the same length, return any of them.
