For example, decimal palindromic numbers that can be created from "8199" are: "1","8", "9", "99", "919" and "989". Among them, "989" has the largest value. Write a function: string solution (string &S); that, given a string S of N digits, returns the string representing the palindromic number with the largest value. Examples: 1. Given "39878", your function should return "898". 2. Given "00900", your function should return "9". 3. Given "0000", your function should return "0". 4. Given "54321", your function should return "5". Write an efficient algorithm for the following assumptions: N is an integer within the range [1..100,000]; string S is made only of digits (0-9).
