A palindrome is a non-empty string that reads the same back- ward as forward. Examples of palindromes include: civic, racecar, aiboh- phobia; all strings of length 1 are palindromes. We would like to find the length of the longest palindrome substring in a given string using dynamic programming. For example, given the input string character, the longest palindrome substring carac has a length of 5. (a) (b) (c) Develop a recursive formula for the length of the longest palindrome substring. Discuss the correctness of your formula. Use your formula to design a bottom-up dynamic pro- gramming algorithm that finds the length of the longest palindrome substring. What is the time complexity of your algorithm?
