This post is about writing a Java program to find the longest palindrome in a given String. Logic for finding the longest palindrome in a given string The solution given here works on the logic that in a palindrome, starting from the center, if two cursors are moved left

Given a string S, find the longest palindromic substring in S. You may assume that the maximum length of S is 1000, and there exists one unique longest palindromic substring. public String longestPalindrome

Longest Palindromic Substring How to find the longest palindromic substring in a string? First we have to answer the question ‘What is a palindrome?” We also need to go through and set matrix[i][i+1] to true if the characters match else the odd indicies can never

In general, the longest palindromic subsequence is not unique. For example, the string alfalfa has four palindromic subsequences of length 5: alala, afafa, alfla, and aflfa. However, it does not have any palindromic subsequences longer than five charactersalfalfa.

I wrote the following code for this problem. The problem is to find the longest palindromic substring. I think it is correct and is working correctly for all the test cases I entered myself. Now, the Stack Exchange network consists of 175 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.

Longest Palindromic Substring A brute-force solution is check with center at and try to retrieve longest palindromic substring during this procedure. As we have to consider cases that length of substrings a odd or even respectively, so we have to traverse through the string twice.

One of the most interesting algorithms is to find the longest palindromic substring in O(n) time. A palindrome is a string that is the same when reversed. For example, `Dr. Awkward` is a palindrome. If we remove non alphanumeric characters and make each

Using dynamic progrmming find longest palindromic substring for a string S. Here is a video solution that finds the longest palindromic substring. The algorithm is explained with the help of examples and animations.Java code is provided in Code Snippet Section.

Manacher’s algorithm can find the longest palindromic substring for every palindromic center in linear time. For example, if the input string is “abbabbba”, then the algorithm can give you the following results (every digit corresponds to a length of palindromic a b b

Given a string, find all possible palindromic substrings in it. The idea is inspired from Longest Palindromic Substring problem. For each character in the given string, we consider it as mid point of a palindrome and expand in both directions to find all palindromes that

A palindrome is a string which reads the same when read from either of the ends. This post in particular talks about palindromic sub sequences. To know more about a sub sequence, please check my post on Longest Common Sub sequence. A palindromic

In this post we’ll see a Java program to find the longest palindrome in the given string. In the given string there may be more than one palindromes but you need to find which one is the longest and display that one. For finding the longest palindrome in the string you

Given a string, find the length of the longest substring without repeating characters. For example, the longest substring without repeating letters for “abcabcbb” is “abc”, which the length is 3. For “bbbbb” the longest substring is “b”, with the length of 1.
