Longest Palindromic Substring Given a string s, return the longest palindromic substring in s. A string is a palindrome if it reads the same forward and backward. Input Specification: The input consists of a single line containing the string s. Output Specification: Print the longest palindromic substring found in s. Constraints: 1 <= s.length <= 1000 s consists of only digits and English letters. Sample Input 1: Sample Output 1: Explanation 1: "aba" is also a valid answer.
