(20pts) In this question, we study the Largest Palindrome Subsequence problem discussed in EX28 again. The exercise developed a dynamic programming algorithm that runs in 0(n*) time. Improve the running time into O (n2). Describe all of: 1. o your basic method explained in 3-10 lines in English, o complete pseudo code, o proof of the algorithm correctness, and o proof of the running time (n2) Make your answers succinct but include everything necessary to reason the above. Hint: The function isPalindrome is called every time the main algorithm checks if sli to j] is a palindrome. This part refers to no previous computation being inefficient. Can you modify isPalindrome to act as a DP algorithm itself
