Find longest palindrome in a string
WebThe fastest algorithm I can think of is applying LCS in a creative way. It can solve this problem in O(N^2) time and O(N^2) space where N is the size of string. LCS (S, reverse (S)) will give you the largest palindromic subsequence, as the largest palindromic subsequence will be the largest common subsequence between the string S and its … WebYou can find our palindrome checker in the code solution (highlighted): Find Longest Substring That is Palindrome. The brute-force approach to finding the longest palindrome in a string is to iterate over all …

WebGiven a string, find the maximum length contiguous substring of it that is also a palindrome. For example, the longest palindromic substring of “bananas” is “anana”, and the longest palindromic substring of “abdcbcdbdcbbc” is “bdcbcdb”. The problem differs from the problem of finding the longest palindromic subsequence. WebFeb 2, 2024 · Given a string S of length N, the task is to find the length of the longest palindromic substring from a given string. Examples: Input: S = “abcbab” Output: 5 …

WebAt the same time, with the help of two auxiliary quantities mid and maxRight, maxRight is used to store the rightmost subscript of the string we scanned. mid is the subscript of the symmetry axis when scanning the right end. note,The rightmost palindrome is not necessarily the longest palindrome. We just use maxRight to identify the scan length. donate to khan academyWebApr 27, 2024 · Suppose we have a string S. We have to find the longest palindromic substring in S. We are assuming that the length of the string S is 1000. So if the string is “BABAC”, then the longest palindromic substring is “BAB”. To solve this, we will follow these steps.
