Give an efficient algorithm to find the longest palindrome that is a subsequence of a given input string. For example, given the input character, your algorithm should return carac. What is the running time of your algorithm? Input X = <x1, x2, ... , xm> Output the longest palindrome...
One possible longest palindromic subsequence is "bbbb". Example 2: Input: "cbbd" Output: 2 Solution classSolution{public:intlongestPalindromeSubseq(string str){intn = str.length(), high, low; vector<vector<int>>dp(n,vector<int>(n,0));for(high =0; high < n; high++) { dp[high][hi...
Objective:Given a string, find a longest palindromic subsequence in it. What is Longest Palindromic Subsequence: A longest palindromic subsequence is a sequence that appears in the same relative order, but not necessarily contiguous(not substring) and palindrome in nature( means the subsequence will ...
