WebLongest Palindromic Subsequence is the subsequence of a given sequence, and the subsequence is a palindrome. In this problem, one sequence of characters is given, we …
WebThe above problem posses an optimal substructure and overlapping property, so dynamic programming can be used to solve the problem. Let the length of given string (s) be n, and longest palindromic subsequence length for s be represented as LPS (s, 0, n – 1). Base Case : Strings of length 1 are always palindrome, that is, LPS (s, i, i) = 1. lithium conversion kits for golf cartsWebMay 12, 2024 · Also known as longest palindromic substring or subsequence, we have to find the longest palindrome in the given string and return it. It is guaranteed that there will always be a palindrome because a single character is also a palindrome.
